Find the offset angle for an axial pump that delivers 50 gpm at 1750 rpm. The volumetric efficiency is 95%. The pump has a nine 0.75 inch diameter pistons arranged on a 6-in piston circle diameter

7. Use the pump map attached, Suppose I want to pump water at 120 gpm against a head of 10 m. a. What size impeller should I use... note it is between two .. do I want the larger or the smaller and why. b. With this impeller, you can read the hp required and the pump efficiency.. report them. c. What input head is required (NPSH)? d. If I use the largest impeller at 120 gpm it should be clear I will generate extra "head" or pressure. What could I do to handle this extra head .. ie to not deliver too much pressure to my system?

Analyze to select the type of the turbine when its diameter is 600 mm, rotational speed is 600 rpm and working under a water head of 120 meters. The buckets deflect the 100 mm diameter jet through an angle of 165°. Take the coefficient of velocity for the nozzle as 0.97. Use Table given below for selection of turbine. Sr. # Specific speed (rpm) Type of turbine 1 8-30 Pelton wheel with one nozzle 30 - 50 Pelton wheel with 2 or more nozzles 50-250 Francis turbine 4 250-1000 Kaplan turbine 2. 3.

If we assume that a given pump requires 7.50 ft of NPSH when operating at 3500 rpm, what would be the NPSH required at 2850 rpm?

Match the following answers Example for dynamic displacement pump Choose... Choose... Positive displacement pump Vane pump Centrifugal pump Lobe pump Develops good vacuum Gear pump Piston pump Widely used in car engine oil pumps

A hydraulic motor has 7.5-in³ volumetric displacement. If it has a pressure rating of 1200 psi and receives oil from a 25-gpm theoretical flow-rate pump, find the motor a. Speed b. Theoretical torque C. Theoretical horsepower
