Given the sketch shown below, the diameter of the plunger Dp = 8 cm. The Ram diameter is Dr = 48 cm. The efficiency is 100%, the stroke of the plunger is 18 cm. The ram has to raise a load F2 = 2kN. Find: A) the force f1 exerted on the plunger. B) the number of strokes needed to raise the load given above by a distance of 10 cm. C) the volume of oil pumped if the load moves by 20 cm ( using plunger force in a ) D) what will be the new diameter of the ram piston if the new load force is 16 times the force exerted in the plunger the diameter of the plunger is kept to 8 cm.
