A hand pump is being used with a stroke of 7 cm3 per pump actuation.How many pump cycles would be required to lift the load 100 mm high? d) Assume you operate the hand pump at a speed of 0.3 Hz. How long would it take to lift the load 100 mm high? e) What is the work and power required from the pump operator? f) Assume now an electric motor is being used that pump at a rate of 3litres / min. How long would it take to lift the load 100 mm? What is the work and power required from the electric motor?
