A fireman standing on a 4.8 m high ladder operates a water hose with a round nozzle of diameter 2.53 inch. The lower end of the hose (4.8 m below the nozzle) is connected to the pump outlet of diameter 4.03 inch. The gauge pressure of the water at the pump is P p(gauge) pump p(abs) Plamp - Patm =25.6 PSI = 176.506 kPa. Calculate the speed of the water jet emerg- ing from the nozzle. Assume that water is an incompressible liquid of density 1000 kg/m and negligible viscosity. The acceleration of gravity is 9.8 m/s. Answer in units of m/s.
