Using the 6 steps discussed in class, complete the following problem: A pump draws water through a piping arrangement at a mass flow rate of 20 lb/s. At the pipe inlet,

the pressure is 14.7 psi, the temperature is 68F, and the water flows at a speed of 10 ft/s. At the pipe exit, the temperature is 68F, the pressure is 20 psi, and the velocity is 40 ft/s. Determine the power required by the pump in hp and Btu/s if the exit is 50 ft above the inlet.
