Figure 8.12 shows a portion of a fire protection system in which a pump draws water at 60°F from a reservoir and delivers it to a point B at the flow rate of 1500 gal/min.
A centrifugal pump driven by a 160-hp motor rotating at 2400 rpm is used to pump 70°F water in a manufacturing plant. The pump operates against a head of 100 ft and has an efficiency of 70%. If this pump is used under a head of 196 ft, what power will be required?
A single-stage centrifugal pump has an impeller speed of 1750 rpm. If the flow rate of water is 60 gal/min, what is the expected head ?
