An air over oil loading dock lift with a 90-gal reservoir is raised by 125 lbf/in.2 shop air piped through a check valve. The reservoir is 2/3 full when the lift is lowered and 1/3 full when the lift is raised. If the raised lift is overloaded sufficiently to lower it, what pressure could be expected in the reservoir?
