A 2-1/2 inch fog nozzle flowing 225 gpm at a pressure of 100 psi will have a reaction of approximately how many pounds?

To determine the reaction force generated by a 2-1/2 inch fog nozzle flowing 225 gallons per minute (gpm) at a pressure of 100 psi, we can use the formula for calculating nozzle reaction force. The reaction force (in pounds) can be approximated using the formula:

Reaction Force (lbs) = (0.0505) × (gpm) × (√(psi))

In this case, we have the flow rate of 225 gpm and the pressure of 100 psi. Now, we can plug the values into the equation:

1. Calculate the square root of the pressure:

√(100 psi) = 10

2. Multiply the gpm by the constant and the square root of the pressure:

Reaction Force = 0.0505 × 225 × 10

= 0.0505 × 2250

= 113.625 lbs

Rounding this result gives approximately 113 pounds. This calculation confirms that the correct answer, which is 113 pounds, accurately represents the reaction force produced by the nozzle under the specified conditions.
