Question

The diagram on the next slide shows a fluid power system for a hydraulic press The following is known: The volume flow rate is 35 gpm. The hydraulic fluid has a specific gravity of 0.87 and v-4.30x104 ft/s. The power input to the pump is 20 hp. The pump efficiency is 80 percent. The filter has a resistance coefficient K-1.85 based on the velocity head in the suction line. All piping is 2-in schedule 40 steel. The total length of all piping is 55 feet. The valve before the pump is a fully open globe value. The check valve after the first 90° standard elbow is a swing type check valve. Compute the following: . The power removed from the fluid by the hydraulic press (report the result in hp) Clearly show all work, any assumptions made and intermediate steps in your derivation. Show the individual energy losses. Report all results in US units (feet, psi, etc.) Hydraulic Press Flow 11.0ft 10.0 ft 2.0ft 3.0ft Filter Flow Pump
