A hydraulic accumulator is designed to reduce pressure pulsations in a machine tool hydraulic system. For the instant shown, determine the rate at which the accumulator gains or loses hydraulic oil.

Qin = 5.75 gpm
Vout = 4.35 ft/s
Dout = 1.25 in.
Note: For a hydraulic accumulator, fluid flows from a tube into a holding chamber which contains both fluid and air, and then flows out of a tube of the same diameter at the same elevation.
