A double acting hydraulic cylinder is hooked up in the regenerative circuit. The relief valve setting is 1000 psi. The piston area is 25 in^2, and the rod area is 7 in^2. If the pump flow is 20 gpm. Find the cylinder speed and load carrying capacity for the:
A) Extending stroke
B) Retracting stroke
FORMULAS:
Cylinder extending speed: Vext = Qp/Ar
" retracting " : Vret = Qp/(Ap-Ar)
" extending load - carrying capacity = F = P * Ar
" retracting " " " = F = P (Ap - Ar)
