The specific heat capacity of motor oil is 2 Kj/ Kg. That means 2kilojoules and kilograms which is how heat is measured.
Maybe evaporation but I wouldn't use the oil in an engine anyway.
Just short of 10 meters.....no matter what. Wells deeper than this MUST have the pump at the bottom of the hole. They don't depend on vacuum to lift the water.
It is the ratio of (mdot*Cp)min/(mdot*Cp)max where the heat exchanger contains two fluids for which the mdot*Cp should be calculated for each to determine which one is greater. by doing so one can define the ability of one fluid to carry thermal/heat energy with respect to the other. so this is a...
you will have to remove the rear seat as the pump is located behind the backrest. To remove the back seat, you need an extension for your socket wrench and remove the two nuts which are about centered where each person sits. Then lift up the seat to clear four guide/retaining clips. Having done that...

Short Answer: In gasses, forces between atoms are not important and the transfer of momentum (hence force, hence viscosity) between different adjacent regions of a fluid is dues to the movement of particles over long distance. Higher temperature means faster movement means higher viscosity in a...
-- If the wood has sunk ... such as teak, ebony, or mahogany ... then its volume is 0.525 L. -- If the wood is floating, then the portion under the water line has a volume of 0.525 L, and the portion above the water line has volume that we can't state with the information given.
The current in the fluid is the result of a difference in temperature at different depths. It's called convection, and it does the transferring of heat from the bottom to the top of the fluid. What sets up the convection currents is whatever it was that added heat to the bottom of it....
It depends on the system, but the basic principles are: - to reduce the cross-sectional area you're exposing (i.e. crouch down whilst riding a bike rather than sitting up straight); - reduce the coefficient of drag (i.e. reduce the roughness of the surface with which the air flow passes over by...
it depends on outside ambient temperature, distance of fall and friction caused by cutting through the layer of air. Changes in temperature will be very minimal to be noticed though.
the shape and size of the molecules that the fluid consists of, if they are big, wavy molecules then the liquid will be viscous because the molecules struggle to move over each other.
Reducing air resistance would give your car better gas mileage, and improve your time in speed skating, cycling, and downhill skiing, among many other sports.

it will mix up with it. so it is not going to float or not going to sink.
Contact your tutor or whoever is in charge of the course.
the mean free path in dependent on pressure, since the mean free path equation state that mean free path=k*T/((2)^(1/2))*P*o so if you double the pressure your actually decreasing the mean free path by half.
It's the principle that pressure, in an enclosed space, distributesin such a way that there is the same pressure everywhere.
Water has a high pressure all the time.
As you say, work is not being done on it and its kinetic energy is constant, but it is losing potential energy. In this case the potential energy loss is being dissipated into turbulence of the fluid, which is a mechanical form of energy, and perhaps some thermal heating due to friction. A good...
If you put a needle metal "fifteen with water that metal crime volume of heavy water is but a needle into the water that does not go to the attraction for surface water..
When they get hotter, gasses and fluids have a lower density (they weigh less per cubic inch) so they rise above the cooler material. Another answer Most of the time a convection current happens within the Earth, in the layer which we call the mantle. Like the rock cycle, it has no certain...
Short answer: Water has a somewhat higher surface tension than many other liquids because the disruption of the forces between molecules at the surface weakens the molecular attraction significantly and the molecular forces were rather large to begin with, so the energy lost in forming the...
When it absorbs enough heat energy to evaporate.
Yes it does. Friction tends to slow down objects in motion, like if you throw a brick through the air, it will not go far, depending on the force you used to throw the brick. Its speed will gradually decline due to the brick's friction with air. Now if you threw a football through the air using the...
at that altitude (stratosphere?) the air density is much less, therefore terminal velocity is much greater
Friction force is equal to the force applied only when the object is not moving or it is just beginning to slide. Once the object has started motion completely, it means that the force applied has exceeded the frictional force
Old house, the pipes fill up with sediment. A 1/2 inch pipe may have a quarter of an inch or less. On some new houses there may be a pressure regulator on the line coming in. Somewhere between where it comes into the house and the first faucet or the water heater, whatever comes first...
one inch of water column = .0361 psi.
The amount of silica in magma
Streamlining allows the layers of fluid (air or water) to pass over the object more easily so reducing friction to the movement of the object.
if we use the ejector or vacuum pump to create vacuum in process tenk .then there may be backflow to the process tank (e g. evaporator) .to avoid that backflow we are using barometric legs.
Hydro means 'fluid' and Hydro-electric means electricity derived from devices driven by fluid. IE a hydro-electric power plant uses the power of water channeled from a dam to drive water turbines which in turn drive the generators that produce the electricity.
The more viscous a substance is, the closer together its molecules are, the more energy required to excite the molecules. Therefore, higher viscosity equals a lower excitability.
Cryogenic Processing of metals (i.e. metals frozen to low temperatures) show more resistance to wear
Brake fluid is a type of hydraulic fluid used in hydraulic brake applications in motorcycles, automobiles, light trucks, and some advanced bicycles. It is used to transfer force under pressure from where it is created through hydraulic lines to the braking mechanism near the wheels. It works...
Pressure 200meters below sea level
It is heat transfer at speed higher than 0.3 Mach.
Buoyant force is the upward force or thrust... Simply, consider immersing your hand inside a bucket of water.... The hand basically comes up (a little) if you just leave your hand... This is due to the buoyant force.... Basically that is the upward force/thrust that acts on any body that is immersed...
In magnetism: An eddy current is induced into a metal when magnetic lines of force move across it. A South pole causes circulating current in clockwise direction while a North pole causes current in counter-clockwise direction. These eddy currents thus buck the applied forces. Eddy currents are...
Basically to reduce air friction on a body, the most general idea is to streamline the body. The same is done by the helmet. When one drives a bike , the person takes a position which streamlines the flow of air over the body(i.e, he bends, like in motoGPs). But the head is not so streamlined and it...
the balloon will just come back up to the water surfuce
Both the friction between the moving body and the liquid, and between the molecules of the liquid. And other intermolecular forces the keep the liquid together (like Van-der-Waal force)
1 Liter (L)= 1000 milliliters (mL) Divide 1 L by 1000mL, then multiply by 4. This gives you .004 Liters.
You may mean a "close-coupled pump" in which case, that is a pump which is mounted directly on the same shaft as the driving motor: i.e. there is no baseplate or coupling to join the two shafts, drive and driven, and the pump hangs off the notor frame. A centrifugal pump is a type of pump where the...
The term artesian means that the water is contained in an underground aquifer and/or reservoir. The fact that it is spouting means that it has artesian pressure and is a flowing artesian well. The geology of the site determines the amount of pressure on the reservoir and not all artesian wells...
because it need air to push the water out.in other words water exiting and air entering the same hole is inpossable.
they are neutrally buoyant. they have ballast tanks to achieve this
Density or specific gravity.
Same as it is on a human, decelerate the descent speed such that the rocket can be used again.
Any substance with a low fluid viscosity can.
Air Resistance is a force . It is a force which act in theopposite direction that you are travelling (except in space, whereair resistance is non-existent). It is caused by molecules ofair colliding with an object , causing it to slow down andeventually stop. Air Resistance can also be known as ...
This can be found from the steam tables. www.x-eng.com gives steam tables. At different temperatures and pressures wolume of water can be found. To find the coefficient of expansion of water, find the volume at 5degree lower and 5 degree higher at same pressure. Take the mean and divide with the...

A buoyant force is produced when an object is completely or partially submerged in a fluid at rest .
All but one (mercury) are solid at room temperature, most of themhave a shiny surface
Wate bending is a mixture of chi and telekinesis combined so you must really meditate
The best way to begin is to read the tiny instruction booklet that comes with each one sold. There you'll find instructions on its use and care, and pictures even.
Yes, a machine can convert mechanical energy into hydraulic energy (i.e., pump water up), and a machine can convert the hydraulic energy into mechanical energy. Some energy will be wasted in both cases , meaning that if you try to do this "back and forth" several times, the total energy available...
Yes. Sound requires a medium to travel in. It is comprised of pressure waves (a mechanical phenomenon). Sound requires something to compress and rarefy (a medium). Sound pressure, or acoustic pressure, is the local pressure deviation from the ambient (average, or equilibrium) atmospheric pressure....

The major losses within a pipe are those that occur through out thelenght of the pipe, they are caused by the interaction of the waterparticles and the inner surface of the pipe as water flows throughit. Now minor losses are those that occur due to fitting andconnections in a pipe sytem, such as 90...
Any liquid exerts equal pressure in all directions.
Yes, gases expand or contract to fill the volume and shape of their containers.
Kinetic energy (K) is one half of the product of mass (m) times the square of the object's velocity (v): K=(1/2)*m*(v squared)
Air pressure decreases as altitude increases.
Yes, it is. Specifically it is a thixotropic fluid since it acts almost as a solid when quiet but becomes more fluid when stirred or shaken. Another Point of View: Tomato ketchup is not a liquid but it contains liquids. It is a suspension of organic solids, primarily of pureed tomatoes in...
terminal velocity . this is because this is the point at which the objects acceleration terminates. in other words, it is the point where the object stops getting faster.
Well since it is buoyant, it rises until it cools enough to begin falling again.
A place where electricity is produced by the energy of rapidly moving water.
no, it warms by compression heating.
Simply stated: boiling point, though it's better to say: volatility . Related Information: Not all substances with different boiling points can be separated by simple distillation. An example is a water/ethanol mixture. The ethanol, in a 50/50 mixture of water and ethanol, can be concentrated...
Yes. The proper term for going from a solid to a gas is sublimation. Boiling is reserved for a liquid to a gas.

That completely depends on what "this" and "it" are.
We don't see bends "sucked" out of rivers. As bends, called meanders, form in rivers, we'll eventually see that the current flow will begin to "cut into" the bank that is confining and turning the flow. That translates into uncercutting and eventual "cutting through" of the bend or meander. If we...
That solution is called saturated .

Water particles (molecules) move transversely to the direction of propagation of the wave. That means that as the wave moves out across the water, which is its direction of propagation, the water molecules move up and down (transversely) to create the crests and troughs of the wave.
venturimeter is a device used for measuring the flow of the fluid.
Metal heated to be soft enough when pulled through hardened dies produces long prismatic sections on cooling, called extrusions. Used in metallurgy, plastics processing.
Skiing and snowboarding (Skis rubbing against snow slows them down) Skateboarding (Rolling friction, it's a matter of opinion if it supports or opposes them) Swimming (fluid friction makes it harder for them to swim against it) Those are just a few.
For a fixed volume, a sphere is the shape with the lowest surface area to volume ratio. Surface tension is minimized when the drop forms a sphere, and molecules always tend toward the position which minimizes energy.
The weight of the water displaced by the object is subtracted from the actual weight of the object (out of water), leaving the object with a net positive weight while submerged.
