Solar collector 1 P2 = Patm h2 Reservoir D D Total equivalent length of L hi Pi = Patm 20 water An engineer uses a solar-powered submersible pump to supply 20C ground water to an above-ground reservoir, as shown in the figure above. If the flow rate into the reservoir is 26.6 L/min, how much input power is required from the solar power source for the pump? Your answer should be in W. The pump is 40% energy efficient. L=34.7 m, D=2.4 cm and the equivalent roughness of the pipe is 0.48 mm. h1=29.2 m, h2=4 m, and the total elevation rise from point 1 to 2 is approximately 33.2 m. Neglect minor losses
