A pump rated at 65% efficiency is used to transport water from a large open reservoir to a point 10m above at a rate of 450 L/min, into a vented tank. Assuming friction is negligible and that the efficiency of the motor is 77%, how much electricity is required to keep the process running for 24 hours? Choices: A. 29.37 kWh B. 35.28 kWh C. 56.71 kWh D. 43.21 kWh
