Question #1: Centrifugal pump is pumping water from a lake. The pump was placed in a height of 6 ft above water level. The diameter of the suction pipe is 2" with a total length of 100 ft; this length already includes the equivalent length of the fittings. The flow rate of the system is 15.5 liter Friction loss in the system is 0.085 ft per 1 ft total length of the pipe. The minimal NPSH required for normal operation of the system is 9 ft. It can be assumed that moving the pump and changing its height (as compared to the water level) doesn't change the friction in the pipe system or its total length. The vapor pressure of water in these operation conditions is 347.7 mmHg. min Determine if the system is properly assembled, suggest changes if necessary.
