Problem #1: A 4.5 kW pump operating at steady state draws in liquid water at 1 bar, 15 °C and delivers the water at 5 bar to a location whose elevation is 6 m above that of the inlet. There is no significant change in velocity between the inlet and exit, and the local acceleration of gravity is 9.8 m/s? Would it be possible to pump 5.5 m in 10 min or less? Explain. (25 pts)

312: A 35 hp pump operates at steady state and is adiabatic and internally reversible. At the inlet the pump has a flow area of 0.04 m² and draws in 52 kg/s of liquid water at 1 bar, 20 °C. At the exit the water is at 4 bar, 15 °C with a flow area of 50 cm. What is the maximum elevation, m, of the pump exit compared to the pump inlet?
