__Nozzle Reaction Force Formula:__

The nozzle reaction force is a measure of the backward force exerted by a nozzle when a fluid (usually water) is discharged at a high velocity. This principle is commonly applied in fire fighting to understand the forces on the hose and nozzle.

Nozzle Reaction Force, NR_{(N)} in Newtons is calculated by multiplying the pressure, P_{(Pa)} in pascals by the nozzle area, NA_{(m2)} in square metres.

Nozzle Reaction Force, NR_{(N) }= P_{(Pa)} * NA_{(m2)}

NR_{(N)} = nozzle reaction force in Newtons, N.

P_{(Pa)} = pressure in pascals, Pa.

NA_{(m2) }= nozzle area in square meters, m^{2}.

__Nozzle Reaction Force Calculation:__

- Calculate the nozzle reaction force if the pressure at the nozzle is 700,000 Pa and the nozzle area is 0.005 m².

Given: P_{(Pa)} = 700,000Pa, NA_{(m2) }= 0.005m^{2}.

Nozzle Reaction Force, NR_{(N) }= P_{(Pa)} * NA_{(m2)}

NR_{(N)} = 700,000 * 0.005

NR_{(N)} = 3500N.

- To find the nozzle area, given the nozzle reaction force is 2000N and the pressure is 400,000Pa.

Given: P_{(Pa)} = 400,000Pa, NR_{(N)} = 2000N.

Nozzle Reaction Force, NR_{(N) }= P_{(Pa)} * NA_{(m2)}

NA_{(m2) }= NR_{(N)} / P_{(Pa)}

NA_{(m2) }= 2000 / 400,000

NA_{(m2) }= 0.005m^{2}.
