In a hydraulic system piston 1 has a surface area of 100 cm2 and piston 2 has a surface area of 900 cm2. Piston 1 exerts a pressure of 10 Pa on the fluid in the hydraulic lift. What is the fluid press?

Using the equation for hydraulic systems (F1/A1 = F2/A2), where F1 is the force of piston 1, A1 is its surface area, F2 is the force of piston 2, and A2 is its surface area, we can calculate the force of piston 2 as 90 N. Since pressure (P) is defined as force per unit area (P = F/A), the pressure exerted by piston 2 on the fluid is 0.1 Pa.
