Water at 255C is pumped at a rate of 300 gpm through a 20 -inch schedule 40 pipe from reservoir 1 to reservoir 2 using a centrifugal pump. Both reservoirs are open to the atmosphere and the water level in both of them is the same. The required net head of this system is given by: h=0.0002Q2+0.0155Q h is the required net head in ft and Q is the volumetric flow rate in epm. The performance curve of the centrifugal pump as provided by the mannfacruner is givea blow Figure 3.1 . Base on the above information and the selected centrifugal pump, Estimate the followings; 1. Select the appropriate impeller size to be used in this pump. 2. Calculate the shaft power of the selected impeller. pt. 2. 3. Using the 11.25" impeller option, is it possible to increase the pumping flow rate to 500 gal/min ? Explain your answer [Marks: 12] Properties of water: =997kg2m2 and 1mPas Figure 3.1
