A fireman standing on an 11 m high ladder operates a water hose with a round nozzle of diameter 2.5 inch. The lower end of the hose (11 m below the nozzle) is connected to the pump outlet of diameter 3.91 inch. The gauge pressure of the water at the pump is P(gauge) Ppump = (abs) Ppump - Patm = 42.4 PSI 292.338 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.
