Firefighters cоnnect а fire hоse tо а hydrаnt and lift the other end of the hose into the air to attack a fire in an upper floor. In the ground just below the hydrant the gauge water pressure is 138 kPa, the pipe has a diameter of 6.0 cm, and the volume flow rate through the pipe is 0.04 m3/s. If the gauge water pressure is zero at the high end of the hose, which has a diameter of 5.0 cm, to what height did the firefighters lift the hose?
