A hydraulic press has a ram of 150 mm diameter and plunger of 30 mm diameter. The stroke length of the plunger is 200 mm and weight lifted is 900 N. If the distance moved by the weight is 1 m in 15 minutes, then determine (i) the force applied on the plunger, (ii) power required to drive the plunger and (iii) number of strokes performed by the plunger.
