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 46 m higher than that of the lower reservoir. If the flow rate of water is measured to be0.03 m /s, determine mechanical power that is converted to thermal energy during this process due to frictional effects. 46 m 20 kW Pump 1kW

1 A pump delivers water from the lower reservoir to the upper reservoir at a rate of 60 L/s. Both the suction and discharge pipes are DN 150 schedule 40steel pipe. The length of the suction pipe leading to the pump is 3.5 m, and 7 m of discharge pipe extend from the pump outlet to the upper tank. There are three standard 900 elbows and a fully open gate valve. The depth of the fluid level inside the lower...

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 (%).

In a hydroelectric power station, the turbine is driven by water flowing from a reservoir at the rate of 551 m s. The water is pumped through a pipe 2.06 km long of 2.53 m intemal diameter with a friction factor of 0.004. The water is assumed to have a kinematic viscosity of 13x10 mʻls. The elevation of the upper reservoir above sea level is 400 m and that of the lower reservoir is 40 m. Determine the following Mean...

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...
