Question

Figure 2 is a schematic of a pumped-storage system. How much power must be supplied to the water by the pump (in kilowatts) to pump water at 0.085 ?3/? at 20?C from the lower to the upper reservoir? Figure 2: Pumping from lower to higher elevation. The head loss in the pipes is ℎ?=0.018 ?/? ?^2/2?, where ? is the length of the pipe in meters, and ? is the diameter of the pipe in meters. Sketch the HGL and EGL for the system.

Figure 2 is a schematic of a pumped-storage system. How much power must
be supplied to the water by the pump (in kilowatts) to pump water at
0.085 m³/s at 20°C from the lower to the upper reservoir?
Elevation = 42.7 m
Elevation - 27.4 m
L= 608 m
D = 20 cm
L= 304 m D= 20 cm
Elevation - 12.2 m
Figure 2: Pumping from lower to higher elevation
The head loss in the pipes is hį
0.018 L v2
where L is the length of the
D 2g
pipe in meters, and D is the diameter of the pipe in meters.
Sketch the HGL and EGL for the system.
