Exercises What fluid conditions are necessary for you to use the following equation for calculating power? What fluid conditions are necessary for you to use the following equation for calculating power? Pwr =-VAP If fluid power is positive in a process, work is done by) the fluid. If fluid power is negative, work is done or by) the fluid. You are selecting a pump for a laser cooling system that uses water. The pump must provide a pressure difference of 42 psi and a volume flow rate of 3.5 ft3/min. You have three pumps from which to choose: ¼hp, ½ hp, and ¾ hp. Which pump would you select? (on or (4 5) What flow rate can be expected from a 1-hp pump that produces a pressure difference of 250 kPa? A piston in a hydraulic cylinder has a power output of 7500 watts when it applies a force of 2000 newtons to a load. (a) At what speed does F=2000 N the piston move? (b) The area of the piston is 40 cm2. What is the volume flow rate into ER Hud

Explanation / Answer

1.

The conditions are as follows:

The fluid should follow uniform flow

Flow should be irrational

There is no headloss due to minor and major losses
