Question

02. centrifugal pump draws benzene at 25°C (sp. weight of benzene 8.59 kN/m) om a tank whose level is 2.6 m below the pump inlet. The atmospheric pressure (abs). The head loss in the suction piping due to friction and minor osses is 0.8 N.m /N. The vapor pressure of benzene is 13.3 kPa (abs). Determine he available net positive suction head (NPSH) and tell f it is acceptable or not. (10 points) Discharge ine Flew 2.6 m What is the most important use of kinetic pumps? If a centrifugal pump is specified as 3 x 4-10, what are the dimensions of suction and discharge pipes? (b) A kinetic pump with 10-inch impeller diameter running at 1750 rpm and consumes about 10 hp power. It delivers 260 gpm of fluid to a 100 ft head. If the pump's impeller diameter reduced to 8-inch, calculate the pump's new performance (capacity, head, and power consumption). (15 points)
