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 19 m3/min. Take the density of water as 1000 kg/m3 and the momentum-flux correction factor as unity.A) Determine the average water exit velocity.The average water exit velocity is m/s.B)Determine the magnitude of horizontal resistance force required of the firefighters to hold the nozzle.The magnitude of horizontal resistance force required of the firefighters to hold the nozzle is N.
