Suppose we have a piston 0.5 cm in diameter pushing on a fluid, and that liquid is connected to a cylinder with another, larger, piston being used to lift up your car. If your car has a mass of 1500 kg, and without the apparatus you can lift at most 41.8 kg, what is the minimum diameter of the piston you will need to lift your car?

LEARN MORE REMARKS In this problem, we didn't address the effect of possible differences in the helghts of the pistons. If the column of fluid is higher in the small piston, the fluid weight assists in supporting the car, reducing the necessary applied force. If the column of fluid is higher in the large piston, both the car and the extra fluid must be supported, so additional applied force is required. QUESTION if the radius of the output piston is...

Suppose that you bring your car to an auto mechanic. The auto mechanic, to get a better look at what’s broke, puts your car on a hydraulic lift, shown below in which there is an incompressible fluid of density € ρ = 900 kg m3 . A force € F1 is applied to a piston of area € A1 . This supports the weight of the car € F2 on the second piston of area € A2. Assume that both...

Fluid Mechanics Question Air flows in a horizontal with an internal diameter of 20 cm at 25oC isothermally. It enters the pipe at a pressure of 500 kPa and leaves at 300 kPa. If the mass flowrate is 10 kg/s and the φ friction faction is 0.002, calculate the length of the pipe. Express your answer in m. You can assume molecular weight of air to be 28.9 g/mol.

Many people have imagined that if they were to float the top of a flexible snorkel tube out of the water, they would be able to breathe through it while walking underwater. However, they generally do not consider just how much water pressure opposes the expansion of the chest and the inflation of the lungs. Suppose you can barely breathe while lying on the floor with a 370 N weight on your chest. How far below the surface of the...

Suppose that we have an axon that is 10 cm long, with an inner radius r1 of 1 μm and outer radius r2 = r1+ 1nm = 1 μm + 1nm. In this exercise, you may use a dielectric constant for cellular fluid of κ = 3. Write an expression for the magnitude of the Electric Field, “E” outside (at an arbitrary radius r) for a uniformly charged cylinder of length “l” with charge “q”: This cylinder is in a...

Consider the following three cases 1. The finger is pushing but not hard enough. Neither block moves 2. The finger is pushing hard enough that the two blocks are speeding up 3. The blodies have sped up, and are now moving at a constant speed. The finger still has to push to keep them going at a constant velodty. In all cases where the blocks are moving, they are moving together. (Block is not sliding on block A.) Block A...
