Hydraulic lift system – Sophiya

Consider the hydraulic lift system in the figure below, with 10
mm rod and 50 mm cylinder, used to lift a 500 kg load.a) A handpump 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? b) 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? c) What is
the work and power required from the pump operator? d) Assume now
an electric motor is being used that pump at a rate of 3 litres /
min. How long would it take to lift the load 100 mm? e) What is the
work and power required from the electric motor
