A pump supplies oil at 20 gpm to a 2- in. diameter double-acting hydraulic cylinder. If the load is 1000 lbs (extending and retracting) and the rod diamerter is 1 in., find:

a. The hydrualic pressure during the extending stroke
b. The piston velocity during the extending stroke
c. The cylinder horsepower during the extending stroke
d. The hydraulic pressure during the retraction stroke
e. the piston velocity during the retraction stroke
f. The cylinder horsepower during the retraction stroke.
