Hello i have an example with an answer , please show the solution since only the answer was shown in this example. And i need its solution to review properly. Thank you 1.Question : An existing pump is used to pump water with the following data at BEP: D = 2.15 in, N = 1784 rpm, ρ = 998 kg/m3, Q = 18 gpm, H = 4.2 ft. A larger pump is to be designed based from the existing one to be used for pumping slurry (ρ = 1220 kg/m3) such that its best efficiency point occurs as close as possible to a volume flow rate of 48 gpm and at a net head of 15 ft. Calculate the new pump diameter in inches. Round off your final answer to 3 decimal placesAnswer: 2.554
