Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Question

The Figure shows the arrangement of a circuit
for a hydraulic system. The pump draws oil
with a specific gravity of 0.90 from a reservoir
and delivers it to the hydraulic cylinder. The
cylinder has an inside diameter of 12.5 cm, and
in 15 s the piston must travel 0.5 m while
exerting a force of 50 kN. It is estimated that
there are energy losses of 3.4 m in the suction
pipe and 10.7 m in the discharge pipe. Both
pipes are 1 cm Schedule 80 steel pipes.
Calculate:
a) The volume flow rate through the pump.
b) The pressure at the cylinder.
c) The pressure at the outlet of the pump.
d) The pressure at the inlet to the pump.

A pump is to deliver 80 GPM of water at a density of 61.38 lb/ft 3 with a discharge pressure of 150 psig. Suction pressure indicates a 2" Hg vacuum.

A pump is used to increase the pressure of water from 105 kPa to 800 kPa at a rate of 160 L/min. If the shaft power input to the pump is 3 kW, the efficiency (expressed in decimals, such as 0.25; don't write 25%) of the pump is ?
A room has a volume of 349 m3. An air-conditioning system is to replace the air in this room every 81.5 minutes, using ducts that have a square cross section.

If you have a flat tire and need to pump up the tire on your car with a hand pump, what force do you have to apply to the pump handle? Assume the air pressure in your tire will be 20 lb/in2, that is 1.1 KPa (138,0000 N/m2). Let the air pump have a cross-section that is 5 cm in diameter. It depends on the weight of the car. About 270 N when the tire is full, not much when you start pumping on the empty tire. About 270 N for as long as it takes from the beginning. Just a few newtons until you are satisfied with how full the tire is because of the hand pump.
