A hydraulic poppet valve is used to relieve high-pressure spikes within a hydraulic circuit. The pressure drop across the relief valve is 6000 psi. What is the expected temperature rise in the hydraulic fluid?

For a fixed nominal flow rate through a rectangular flow passage, determine the flow gain for a valve with its nominal opening given by 1/10, 1/4, 1/2, 3/4, and 9/10 of the maximum opening of the valve.
