Which of the following statements about smooth bore nozzle reaction is MOST accurate?
A) Lean backward to control nozzle as action increases.
B) Nozzle valves should be opened slowly to minimize water hammer.
C) Increasing discharge pressure and flow rate increases nozzle reaction.
D) Additional personnel are required for operating smooth bore nozzles on all hoselines.

Question

Quizplus · Accepted Answer

Increasing discharge pressure and flow rate directly increases nozzle reaction, as the force exerted by the nozzle is a product of the discharge rate and the velocity of the water.
