3_12: A pump operating at steady state draws in 60 kg of liquid water per second at 1 bar, 15 °C and delivers the water to a location whose elevation is 10 m above that of the inlet. The exit pressure is 4 bar and the temperature remains constant. The inlet has a diameter of 20 cm and the exit has a diameter of 10 cm. The pump operates adiabatic and experiences no internal irreversibility. If pumps are sold in...

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?

Storage tank 18 m Pump Water is pumped from a lake to a storage tank 18 m above at a rate of 64 L/s while consuming 21.2 kW of electric power. Disregarding any frictional losses in the pipes and any changes in kinetic energy, determine (a) the overall efficiency of the pump-motor unit and (b) the pressure difference between the inlet and the exit of the pump. b) AP- a) 1 kPa

(5 pts) A pump is pumping water from a lake to the top of a mountain through a constant- diameter pipe. Water exits the pipe at a volumetric flow rate of 0.04 m/s. The vertical distance between the lake surface and the pipe exit at the top of the mountain is 100 m. The diameter of the pipe is 10 cm. All mechanical energy losses are negligible and the flow is steady and incompressible. (Water density-I g/cm, ?-I.) Determine a)...
