1. A pump is connected between two tanks as shown in Figure. 1.1 Calculate the pumping head for a flow at 20 liter per min. (5 pts) 1.2 Calculate NPSHA of this pump. (3 pts) Q 78 mm ID Q53 mm ID 3 atm 7 m 3 m 2 + Valve Valve Pump 14 m 7 m Commercial Steel Fitting Globe valve 90 Elbow Number of fitting 2 1 Water Properties 30 C Density 996 kg/m viscosity 8*10-4 kg/m s Vapor Pressure 4.2 kPa 2. From Problem 1, If the Head pump is XY meter. Calculate the flow rate ? (7 pts) Note 1. XY come from last two digits of your student number, for example Your student number is 6510683048, then X=4 and Y=8 2. If you XY=00, you may assume the pump head equal to 30 m
