An object floating on the surface when a wave passes?
== == == == The object is moving the speed of the water, not the speed of the wave. Example: when you are riding in a car, you are moving the the speed of the car not the speed of the bump in the road. The bumps in the water are mostly caused by wind & are like bumps in the road, but these bumps move. in an ellipse
What are the uses and limitations of flow net in fluid mechanics?
Flow nets are used to visualize and analyze flow patterns in 2D problems with steady-state and incompressible flow. They help in understanding the velocity and pressure distribution within a domain. However, flow nets are limited in that they do not provide information about 3D flow behavior, transient flow phenomena, or turbulence effects. Additionally, they are not typically used for complex geometries or non-ideal fluid behaviors.
Water moving along the ground's surface?
Water moving along the grounds surface is called a river or a flood.. A river or a flood both contain moving water. River water is consistently moving. A flood will have water moving until it goes away.
The leak in the hull will cause water to enter the hold, filling it up. Since the hold is open to the atmosphere, water will continue to fill up the hold until it reaches the same level as the lake. This will cause the ship to sink.
The inverted drinking glass must be pushed to a depth where the water level inside the glass is halfway between the original water level and the top of the glass. This ensures that the volume of enclosed air is squeezed to half.
Under constant pressure the volume of a gas and its kelvin temperature are?
Directly proportional.
Related Information:
According to the Ideal Gas Law (PV=nRT) if the Pressure P is held constant and the Temperature is increased, the Volume will also increase.
Will there be any flow variations if a venturimeter inlet outlet connections is reversed?
Yes, reversing the inlet and outlet connections of a venturi meter will result in flow measurement errors. The design of the venturi meter relies on the inlet and outlet connections being in a specific orientation to accurately measure fluid flow rates. Reversing the connections disrupts the flow dynamics and can lead to inaccurate readings.
How do you calculate the force exerted on an object in a well flowing at a given rate?
To calculate the force exerted on an object in a well flowing at a given rate, you can use the formula: Force = Pressure x Area. First, calculate the pressure at the depth of the object in the well using the fluid's density, gravity, and depth. Then, determine the cross-sectional area of the object to which the pressure is being applied. Multiply these values to find the force exerted on the object.
What is used to control the three methods of heat transfer?
Heat transfer can be controlled using various methods such as insulation to reduce conduction, air circulation to enhance convection, and reflective surfaces to minimize radiation. Additionally, temperature control systems like thermostats or heat exchangers can also be used to regulate heat transfer within a system.
Answer #1: it is complicated flow
========================
Answer #2:
Tortuous flow is flow along a path with many twists, turns, and bends in it.
The term refers to the path of the flow, and I think the flow itself may be laminar.
Mechanical pressure is the force applied to an object by another object in contact with it. It is the physical force exerted on a material that can cause a change in its shape or volume.
What is the explanation for a feather quilt being so warm on a cold winter night?
Normally, only the fluffy down near the base of the feather is used for bedding. The fibers in down are hollow and tend to be puffy, rather than well ordered like the rest of the feather. Because the down is hollow and fluffy, it traps a boundary layer of air near your body. Heat from your body heats the trapped air in among the down fibers. Since the trapped air does not move around much, it acts as an insulating barrier between you and the cold air in the room.
Can an experiment that has several variables be used to explain theory?
Yes, an experiment with several variables can be used to test and provide evidence for a theory. By manipulating and controlling the variables, researchers can investigate the relationships between them and how they affect the outcomes, helping to support or refute theoretical predictions. However, it is essential to design the experiment carefully to ensure that the results are reliable and can contribute to a better understanding of the theory.
What is the calculus operation for finding the rate of change in an equation?
The calculus operation for finding the rate of change in an equation is differentiation. By taking the derivative of the equation, you can find the rate at which one variable changes with respect to another.
What is the difference between Gay Lussac's Law and pascal's principle?
Gay Lussac's Law states that the pressure of a gas is directly proportional to its temperature, when volume and amount of gas are held constant. Pascal's principle, on the other hand, states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and the walls of its container.
What is the pressure in pascals for 1000N on 30cm2 of area?
The pressure can be calculated using the formula: pressure = force / area. In this case, the force is 1000N and the area is 30cm^2 (which is equivalent to 0.003m^2). So, the pressure would be 1000N / 0.003m^2 = 333,333.33 Pascals.
The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being precisely equal to 101.325 kPa. It is equivalent to 760 mmHg (torr) or 29.92 inHg. One standard atmosphere is standard pressure used for pneumatic fluid power (ISO R554), and in the aerospace (ISO 2533) and petroleum (ISO 5024) industries.

What is the efficiency of hydraulic generators?
Basically, you need to calculate the amount of energy contained in the fuel you use to produce a given amount of electrical energy. To calculate the amount of energy in the fuel you need to lookup the number of thermal energy units per unit volume then you can convert those thermal energy units into Joules (1 gallon [U.S.] of diesel oil = 146 520 000 joules - www.onlineconversion.com) The on the electrical side, just multiply the voltage by the current by the number of seconds of run time (unvarying load) to get the electrical power output in Joules. Then the efficiency is just the the output power divided by the input power (x100 for %).
Sphere radius, R = (28 cm)/2 = 14 cm = 0.14 m
Speed, v = 2 m/s
Mass, M = 2.5 kg
Rotational KE = ½𝙸𝜔²
For solid sphere, the moment of inertia, 𝙸 = ⅖MR²
Rotational KE = ½(⅖MR²)(v/R)²
= ⅕Mv²
= ⅕(2.5 kg)(2 m/s)²
= 2 J
Total KE = Linear KE + Rot KE
Total KE = ½Mv² + ⅕Mv²
Total KE = (7/10)(Mv²)
Total KE = (7/10)(2.5 kg)(2 m/s)²
Total KE = 7 J
Angular momentum, 𝜔 = v/R = (2 m/s)/(0.14 m) = 14.3 rad/s
How do you drop an egg using a parachute - without cracking the egg?
How about use a plastic cup drill holes on both sides use a string put through the holes tie the ends to a plastic bag and, voila, a parachute for the egg.
More Information:
The parachute must be big enough and of appropriate material to slow the fall of the egg and the parachute. Also, a nice soft field might be a better landing zone than a paved parking lot. Some trial and error experimentation will probably be necessary to get the right chute area to weight ratio. Don't start with the egg.

Capillary rise and fall applications in nature?
Capillary rise in plants helps in the transportation of water from roots to leaves. In insects, capillary action assists in the movement of liquids through small channels like tracheae and tracheoles. In sea sponges, capillary action helps in filtering and absorbing nutrients from water.
What is the maximum lift coefficient of a NACA-4412?
The maximum lift coefficient of a NACA-4412 airfoil is typically around 1.4 to 1.5 in ideal conditions. This value can vary depending on factors such as angle of attack, Reynolds number, and airfoil surface condition.
