Water passes along the hose of diameter 2.5 cm and out through nozzle of end diameter 1 cm at a rate of 2kg/s. Density of water is 1000Kgm-3

(a) Calculate volume flow rate (b) Find speeds of water as it passes through the hose pipe and put of nozzle (c) Calculate rate of change of momentum of water as it flows along the nozzle (d) the force which has to be exerted to keep the hose pipe still
