The liquid is pumped into the cylinder at a pressure of 400 kPa. Calculate the force of pressure

The liquid is pumped into the cylinder at a pressure of 400 kPa. Calculate the force of pressure acting on a piston with an area of 250 cm2.

Initial data: P (created fluid pressure in the cylinder) = 400 kPa; S (the area of the piston on which the fluid exerts pressure) = 250 cm2

SI system: P = 400 kPa = 400 * 10 ^ 3 Pa; S = 250 cm2 = 250 * 10-4 m2.

The force of pressure on the piston of the hydraulic cylinder can be calculated from the formula: P = F / S, whence F = P * S.

Let’s calculate: F = 400 * 10 ^ 3 * 250 * 10 ^ -4 = 10,000 N (10 kN).

Answer: The force of pressure on the piston of the hydraulic cylinder is 10 kN.
