Hydraulic cylinder tonnage.

[cybrfire]

Anybody know how to figure the tonnage of a cylinder at a given PSI??

Oh, and how much Pressure does your run of the mill Power steering pump produce?

Looking like 1000 - 1500 psi on the pump. At least that is what i'm finding on the net.

If your asking how much force is exerted by the piston at a given pressure, multiply the pressure by the surface area of the final piston. Keep the units dimesionally homogenous.

(At 1000 PSI, a cylinder with a piston of 3 in^2 will be exterting an force of 3000 pounds), etc...

i just checked gm specs on pumps. just used specs from 2001 model year pumps. looks like pressure relief occurs between 1425 and 1525 psi. looks like the highest flow is about between 3.5 and 3.9 gallons per minute (a 3500 pump w/hydroboost).

Thanks guys. I figured thats what the calculations were. Leading me right to the pump not getting it done.
