Water is pumped from a lower reservoir to a higher reservoir by a pump that provides 20 kW of shaft power. The free surface of the upper reservoir is 45 m higher than that of the lower reservoir. If the flow rate of water is measured to be 0.03 m3/s, determine (a) mechanical power that is converted to thermal energy (in kW) during this process due to frictional effects and (b) the pump efficiency (%). Take the density of water...

Q2. 50 marks Water at 20°C is pumped at 5.7 m3 min-1 from the lower to the upper reservoir, as in Fig. 2. The free surface of the upper reservoir is at height Z2 = 46 m, and of the lower reservoir at 21 = 15 m. The pipe diameter before and after the pump is D= 15 cm. Pipe friction losses are approximated by h = 27v2/(29), where V is the average velocity in the pipe. The gravitational acceleration...

Q3 (40 pts): Water is pumped through a 60-m-long, 0.3-m-diameter pipe from a lower reservoir to a higher reservoir, which has a water surface 10 m above the lower one. When the pump adds 40 kW to the water the flowrate is 0.20 m/s. Assume the following coefficients of minor losses: • Entrance: Kentrance = 0.5 Exit: Kexit = 1 Each elbow: Kelbow = 1.5 • Valve: K= 6 Part A (20 pts) Determine the pipe roughness ε. Part B...
