A worker is pressure washing a deck 4.7 meters above an alligator pond. The pressure washer produces 10 liter per minute steam of water through a nozzle with a diameter of 2.5 millimeters. A 12V battery supplies power to an electronically powered centrifugal pump that draws water from a pond. Assuming a 50% efficient system, what is the amount of electrical current that the battery must supply?
