A fire pump delivers water through a 15 cm main pipe to a hydrant to which is connected an 8 cm. hose, termination in a nozzle 2 cm in diameter. The nozzle, trained vertically up is 1.60 m above the hydrant and 12 m above the pump. The headlosses as follows: pump to hydrant: 3 m. ; at the hydrant 2 m. ; Hydrant to nozzle 12 m. and at the nozzle: 6 % of the velocity head of the nozzle. If the gage pressure at the pump is 550 kPa, to what vertical height can

Question
A fire pump delivers water through a 15 cm main pipe to a hydrant to which is connected an 8 cm. hose, termination in a nozzle 2 cm in diameter. The nozzle, trained vertically up is 1.60 m above the hydrant and 12 m above the pump. The headlosses as follows: pump to hydrant: 3 m. ; at the hydrant 2 m. ; Hydrant to nozzle 12 m. and at the nozzle: 6 % of the velocity head of the nozzle. If the gage pressure at the pump is 550 kPa, to what vertical height can the jet of water thrown? Show its FBD.
Choices:
A.29.5 m
B.25.5 m
C.27.5 m
