1. A hydraulic motor provides torque to a load through a shaft turning at 632 rev/min. The motor has 29 gal/min of fluid going through it, and the pressure at the motor inlet is 2,191 psi. What torque (in ft-lb) is the motor providing? (Assume 100 % efficiency).

2. Fluid is flowing at a velocity of 2 ft/s in a 0.6 in. ID pipe. The pipe transitions to an ID of 3 in. What is the fluid velocity (in ft/s) in the larger pipe?

3. An automobile that weighs 8,945 N is lifted 3 m in 10 s. How much power was delivered to the car (in kW)?

4. A liquid fuel stores energy chemically. The higher heating value (HHV) of a fuel is the energy stored in a fuel per unit of mass. For gasoline, the HHV is 47,600 kJ/kg. If the density of gasoline is 0.735 kg/L, how many joules of energy are in a gallon?
