Two electric pumps are being used to pump water to a cistern at the top of a 50 meter hill. A meter is used to measure the electrical energy in kWh consumed by both pumps over a six-hour period. Both pumps consume the same kWh of electrical energy over the pumping period. If we know that pump #1 has an efficiency of 40% and pump #2 has an efficiency of 80%, what can we say about the volume of water moved by each pump? Assume both pumps use the same piping system, so hydraulic frictional losses are the same for both pumps. O pump #1 moved twice as much water as pump #2 O pump #2 moved twice as much water as pump #1 both pumps moved the same amount of water

![Two electric pumps are being used to pump water to a
cistern at the top of a 50 meter hill. A meter is used to
measure the electrical energy in kWh consumed by
both pumps over a six-hour period. Both pumps
consume the same kWh of electrical energy over the
pumping period. If we know that pump #1 has an
efficiency of 40% and pump #2 has an efficiency of
80%, what can we say about the volume of water
moved by each pump? Assume both pumps use the
same piping system, so hydraulic frictional losses are
the same for both pumps.
pump #1 moved twice as much water as pump
#2
pump #2 moved twice as much water as pump
#1
both pumps moved the same amount of water](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F47d7a0f8-4e66-40ed-ae66-faa7d8f664d3%2Fbe066f7c-4f3a-4c44-aeb8-2832bf176e35%2Fjhx541n_processed.jpeg&w=3840&q=75)
