Afirefighting team operate a firehose from 1.5 m above street level to direct a stream of water at a closed window whose centre is 10 m above the street. the firehose is 110 mm diameter with a 40 mm nozzle and is delivering 1200 l/min of water at the target. a head loss of 0.7 m occurs between the nozzle and the window, due to air resistance to the jet flow (this effect is visible as the jet breaks up into droplets and is not a perfect parabola.) a) how far back must the team stand to hit the window horizontally? at what angle should they hold the nozzle? head loss is equivalent to a reduced parabola height. b) how much force must the team exert to hold the reaction force at the nozzle? what weight of water would they need to carry to hold the hose at that height and angle? c) if these (old) windows are known to break with a central load of 120 n, can they break the window with the stream of water?
