| The diameter of the large cylinder of the hydraulic machine is 50 cm and the diameter of the small cylinder is 4 cm. What is the power gain of this machine?
Since the fluid pressure is assumed to be the same for two cylinders, the ratio F1 / S1 = F2 / S2 will be valid.
Hence: F1 / F2 = S1 / S2, where S1 is the surface area of the large cylinder, S2 is the surface area of the small cylinder.
For a circle, the area is S = (ΠD ^ 2) / 4.
F1 / F2 = S1 / S2 = ((ΠD1 ^ 2) / 4) / ((ΠD2 ^ 2) / 4), where D1 = 50 cm, D2 = 4 cm.
F1 / F2 = (D1 ^ 2) / (D2 ^ 2) = (50 ^ 2) / (4 ^ 2) = 2500/16 = 156.25.
Answer. The power gain for the hydraulic machine is 156.25.
