Firefighters are holding a nozzle at the end of a hose while trying to extinguish a fire. The nozzle exit diameter is 8 cm, and the water flow rate is 21 m3/min. Take the density of water as 1000 kg/m3 and the momentum-flux correction factor as unity. Determine (a) the average water exit velocity and (b) the horizontal resistance force required of the firefighters to hold the nozzle.
