1. A plant is located at an altitude where the atmosphericpressure head is 31 ft of water and the vapor pressure is 9.34 psi.The pump is placed 10 ft below the water tank with a total suctionpipe length of 25 ft, pipe diameter 3 in., and friction coefficient0.02. Assuming the given atmospheric pressure in the tank (where z1= 10 ft and negligible velocity) and if the flowrate provided is180 gpm, determine the available NPSH (ft). Neglect minor losses.ans 17.4 ft
