A fireman standing on an 8.9 m high ladder operates a water hose with a round nozzle of diameter 1.35 inch. The lower end of the hose (8.9 m below the nozzle) is connected to the pump outlet of diameter 2.34 inch. The gauge pressure of the water at the pump is P (gauge) pump = P (abs) pump − Patm = 31.7 PSI = 218.564 kPa . Calculate the speed of the water jet emerging from the nozzle. Assume that water is an incompressible liquid of density 1000 kg/m3 and negligible viscosity. The acceleration of gravity is 9.8 m/s 2 . Answer in units of m/s
