Question:
10.12 A pump (Peerless 8AE20G, Appendix C) with the 20-in impeller operates at 1775 rpm at maximum efficiency. It supplies the pipe-line shown in the figure. Determine the pipeline loss coefficient K in the equation hL = KQ2, with Q in gpm. Determine the flow rate between the two reservoirs if two of these pumps operate in parallel, assuming the pipeline K value remains unchanged
10.13 Data from tests of a pump with a 12.3-in.-diameter impeller operated at 1450 rpm are
Develop and plot a curve-fit equation for NPSHR versus volume flow rate in the form NPSHR=a+bQ2, where a and b are constants.
If the NPSHA =20 ft, estimate the maximum allowable flow rate of this pump.
