Question

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 pressure on piston 2?

Answer 1

Hi! So, I did research and affirmed my thought that I posted and deleted because I was unsure of it. You're not responding to my posts, so I'll just give you some information to help you out.

Here's what happens. Piston one puts pressure on the fluid. In turn, the fluid puts that pressure on piston two. Right?

Answer 3

This is a fairly simple question involving Pascal's Law. Pascal's Law states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same.

In this problem, the output area is 9 times larger than the input area...so the fluid pressure on the output side is is 9 times larger...or 90 pascals. This makes sense because the force per unit area is consistent throughout the system and all you've done is increased the area by a factor of 9.

Answer 4

pressure is same that means..pressure is 10 Pa at piston 2 but force on piston 2 is increased..
