Fluid Dynamics

The additive property of parachor suggests that the parachor value of a mixture can be calculated by summing the parachor values of the individual components. This can be justified by understanding that the parachor value is a measure of the cohesive energy density of a substance, which depends on its molecular structure. The constitutive property of parachor, on the other hand, implies that the parachor value is a fundamental property of a substance, determined by its chemical composition and structure.

The viscosity of air provides a drag force on a raindrop and keeps it from falling with the acceleration of gravity. When a drop is falling (assuming it does not combine with other drops in the process) it will reach a terminal velocity which depends on its diameter. The larger the diameter the larger the terminal velocity. Specifically, the terminal velocity is proportional to the square root of the diameter of the drop.

Big rain drops fall faster than small rain drops.

Volume of a gas at STP (standard temperature and pressure) refers to the volume that a gas occupies when measured at a temperature of 0 degrees Celsius and a pressure of 1 atmosphere. This volume is typically given in liters or cubic meters.

The maximum length of the straw can be calculated using the concept of hydrostatic pressure. By reducing the atmospheric pressure by 85 percent, the maximum height difference the lemonade can be lifted is about 11.72 meters, corresponding to the pressure difference. Therefore, the maximum length of the straw would be approximately 11.72 meters.

Pascal is the s.i unit of upthrust

No, surface tension is not responsible for wave formation in bodies of water. Waves are typically formed by the interaction of wind with the water's surface, causing the water to move in a rolling motion. Surface tension, which is the result of cohesive forces between water molecules at the surface, does not generate waves.

Yes, plasma is considered a state of matter where the particles are ionized. Plasma is often referred to as the fourth state of matter, distinct from solids, liquids, and gases, as it is composed of ionized particles that can conduct electricity. Fluids typically refer to liquids and gases, while plasma exhibits unique properties due to its ionized nature.

pressure loss and friction loss in a pipe can be reduced by 1) using smooth pipes 2) Using straight pipes, because the more bends a pipe has the more energy it will lose. 3)pumping downhill where possible.

Objects that are less dense than water will float, while objects that are denser than water will sink. For example, wood, plastic, and cork typically float in water, while metals like lead and iron sink. The shape and size of an object can also affect whether it floats or sinks.

Yes, pressure exerted by a moving stream of fluid is generally greater than that of a stationary fluid due to the added kinetic energy involved in the flow. This increase in pressure is described by the Bernoulli's principle, which states that as the speed of a fluid increases, its pressure decreases and vice versa.

As the plane hits the deck, its kinetic energy is 1/2 (its mass) x (its speed)2,

so that's the amount of energy that has to go somewhere in order to bring

the plane to a complete stop where its kinetic energy is zero.

My guess at the moment is that the energy must be dissipated in one humongous

shock-absorber at each end of the cable. Springs don't dissipate the energy ...

they only store it, and then it still has to go somewhere. Shocks dissipate it.

The speed at which objects move through water is affected by several factors, including the shape and size of the object, the density and viscosity of the water, and the presence of any obstacles or currents that may impede its movement. Additionally, the force exerted on the object and the surface area in contact with the water also play a role in determining its speed.

This is a bad sign. If the water is in the crankcase this can mean that the head gasget has been blown and the water has leaked into places it should not go. Do not drive this vehicle until the problem is fixed.

To plot a velocity triangle, you can start by drawing a line to represent the direction of the incoming flow. Then draw a line representing the relative velocity of the fluid. Finally, draw a line representing the velocity of the blade. The angles between these lines represent the velocities and can be used to calculate various parameters in turbomachinery analysis.

Renewable fuels, such as solar, wind, and hydropower, cause minimum environmental pollution as they produce little to no greenhouse gas emissions or air pollutants during operation. These fuels are sustainable and have a low environmental impact compared to fossil fuels.

The flow range of a gas flow meter is the range of flow rates that the meter is capable of measuring accurately. It typically includes a minimum and maximum flow rate that the meter can reliably detect and measure. It is important to ensure that the flow rates being measured fall within the specified flow range of the gas flow meter for accurate readings.

A sewing needle is typically made of metal, such as stainless steel or nickel-plated steel, to provide durability and strength for sewing various fabrics. Some specialty needles may have coatings or finishes to help reduce friction and prevent rust.

No. The purpose of a compressor is not to cool it is to compress. A freon compressor keeps freon under pressure to restore its liquid state. If you tried to run oil trhough it the compressor would probably blow up pretty quickly because you can't compress a liquid. You can compress a gas to a liquid but it won't compress beyond that. For an external oil cooler go to a junk yard and get a heater core or even a factory oil cooler from a transmission.

The diffusion coefficient of Fluorescein in water is approximately 4.8 x 10^-6 cm^2/s at 25°C.

Small bubbles rise slowly because of their size and buoyancy. As small bubbles have a higher surface area to volume ratio, they experience more drag as they move through the liquid, causing them to rise more slowly. Additionally, the buoyant force acting on the small bubbles is relatively weaker compared to larger bubbles, further contributing to their slow ascent.

The ability of a liquid to resist flow because of its internal property is viscosity. Viscous liquid refers to liquids that are supercooled, highly viscous, and able to form a glass all at the same time.

Pressure changes more rapidly with height compared to density. This is because pressure decreases exponentially with height due to the decrease in the weight of air above, while density decreases more gradually with height as a result of the decreasing number of air molecules.

Alcohol can adhere to the surface of a glass, especially if the glass has not been properly cleaned or if there are residues present. This can create a thin film on the glass. Regular washing with soap and water can help remove this residue.
