A centrifugal pump is used to pump water at 80F through a pipe system. The water level in both tanks is at 10ft above the pump centerline. The piping is made of cast iron. The centrifugal pump operates at 1750 rpm. The pump performance curve can be represented by H = Ho - AQ^2 where Ho = 14ft and A = 8.6^-6 ft/(gpm)^2. a) Calculate and plot the system curve for this system b)Determine the system design/operating point graphically c) Calculate the pump efficiency at volumetric flow rate of 30m^3/h if power supplied to the pump is 285 W.
