A fluid power system uses oil with a specific gravity of 0.92 and is made up of a reservoir, pump, pressure line filter, and hydraulic motor (rotary actuator) shown below has a flow rate of 668 L/min. The inside diameters of the inlet line is 71 mm, pressure line is 59 mm and return line is 62 mm. The pump efficiency is 82 % and requires 20.5 kW of input power. The energy loss between points 1 and 2 is 0.9 m. between points 3 and 4 is 9.5 m and between points 5 and 6 is 1.7 m. Determine the velocities at points 1 to 6. Determine the elevations of points 1 to 6. Determine the pressures at points 1, 4, 5 and 6. Determine the head removed from the fluid by the motor in N.m/N and the power removed from the fluid by the motor in kW. Submit Assignment Quit & Save Back Question Menu -
