Apump creates a water pressure of 1 mpa in the supply line to a 65-mm-diameter, 300-m-long hose with a roughness height of 0.5 mm, the end of the hose is at an elevation 2.8 m higher than the beginning of the hose. the objective is to place a nozzle at the end of the hose that will create a jet of water that rises 15 mn into the air part a if the local head loss coefficient of the nozzle is 0.04, what nozzle diameter should be used? assume water at 20 c
