A pump is attached to a fire hydrant to produce a jet that rises to a minimum height of 13.5 m at a rate of 20 L/s. The pressure is estimated as 100 kPa at the attachment. The hose attached to the pump is 75 mm in diameter and 1.5 m long with a discharge nozzle at the end. The nozzle is inclined at an angle of 50 degrees to the horizontal. The pump has an efficiency of 80%. Neglect friction. Jet 13.5 m
