Oil at 24 gpm and 1200 psi enters the low-pressure inlet of a 4:1 Racine pressure intensifier. Find the discharge flow rate and pressure. Problem 5 Oil at 155F and 2250 psi is flowing through a pressure relief valve at 25 gpm. What is the downstream oil temperature? Note 1 hp 42.4 Btu/min. Also, for oil under consideration, Specific heat = 0.42 Btu/lb/F 1 gpm = 7.42 lb/min Problem 6 A hydraulic pump operates at 150 bars and delivers oil at 0.0015 m/s to a hydraulic actuator. Oil discharges through the pressure relieve valve (PRV) during 50% of cycle time. The pump has an overall efficiency of 87%, and 15% of power is lost due to frictional pressure losses in the hydraulic lines. What heat-exchanger rating is required to dissipate all the generated heat?
