A pump is attached to a fire hydrant, where it is desired to produce a jet that rises to a maximum height of 40 m and delivers water at a rate of 100 L/s. At the attachment location, the diameter is 100 mm and the pressure is estimated as 150 kPa. The discharge nozzle has a diameter of 80 mm and is inclined at an angle of 50 degrees to the horizontal. If friction losses are neglected, estimate the head that must be added by the pump to achieve the desired objective. The path of the water jet is parabolic.
