A 32 inch diameter pump handling 22000 GPM flow of water comingfrom an atmospheric tank storage is running at 1170 rpm. The watertemperature can be taken at 25 C. The suction line is 20 meter longat 6 inch diameter. The pump suction is 0.4 meter above groundlevel. The tank storage is elevated on a 1 meter high platform.Assume friction factor of 0.02. Specific Gravity of water at 25 Cis 0.9967. NPSH required is 34 ft. Determine: A) NPSHA in terms offeet, B) Will cavitation occur, yes or no? C) BHP D) the specificspeed., E and G) if new speed is 900 rpm with same impellerdiameter, determine the new flowrate in GPM and new head in ft?
