An 11.5-in-diameter centrifugal pump, running at1750 r/min, delivers 850 gal/min and a head of 105 ftat best efficiency (82 percent). (a) Can this pump operateefficiently when delivering water at 20°C through200 m of 10- cm-diameter smooth pipe? Neglect minorlosses. (b) If your answer to (a) is negative, can thespeed n be changed to operate efficiently? (c) If youranswer to (b) is also negative, can the impeller diameterbe changed to operate efficiently and still run at1750 rev/min?

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
