We want to use the 12.75-in pump of figure at 1160 rpm to pump water at 60F from one reservoir to another 30 ft higher through 5000 ft of 6-in-ID pipe with constant friction factor f= 0.020. (a) Determine the system pump equation of the form, h,= a +b Q (b) Plot the system curve on figure and determine the operating point for the 12.75-in pump, detemine its flow (in gpm), head (in ft), efficiency and bhp (in hp). Neglect minor losses. Curve no. 2313 Min. Imp.
