Question
We want to pump subsoil water at a rate of 6 L / s by means of a submerged pump, with 90% overall efficiency, to a pond whose free surface is 25 meters above the surface in the lake. The water inlet to the pump is 1 m below the surface in the lake, where the pressure is 1.1 atm. Neglect variations in kinetic energy and determine:
Data:
1 atm = 101.325 kPa
PATM = 1 atm
Water density = 1000 kg / m3
a) The electrical power consumed by the pump, in kW
b) What is the daily electricity consumption (in kWh) if the 30 m3 capacity tank is filled 2 times a day?
