What is the estimated flow from a 2-inch nozzle with ideal nozzle pressure using the formula gpm = 29.7 X d2 X NP?

What is the estimated flow from a 2-inch nozzle with ideal nozzle pressure using the formula gpm = 29.7 X d2 X NP?

• A. 950 gpm
• B. 1063 gpm
• C. 1190 gpm
• D. 1350 gpm

Answer: (B)

To determine the flow from a 2-inch nozzle using the formula \( \text{gpm} = 29.7 \times d^2 \times \text{NP} \), it is necessary to first understand what each variable in the equation represents. The variable \( d \) represents the diameter of the nozzle in inches, and \( NP \) represents the nozzle pressure in pounds per square inch (psi), which we typically assume to be at an ideal level of 100 psi for calculations unless otherwise specified. In this case, since the diameter is given as 2 inches, you will square the diameter: \[ d^2 = 2^2 = 4 \] Assuming the ideal nozzle pressure (NP) is 100 psi, you can substitute these values into the formula: \[ \text{gpm} = 29.7 \times 4 \times 100 \] Calculating this: \[ \text{gpm} = 29.7 \times 4 = 118.8 \] \[ \text{gpm} = 118.8 \times 100 = 11880 \] Oops! That value seems too high for g

To determine the flow from a 2-inch nozzle using the formula ( \text{gpm} = 29.7 \times d^2 \times \text{NP} ), it is necessary to first understand what each variable in the equation represents. The variable ( d ) represents the diameter of the nozzle in inches, and ( NP ) represents the nozzle pressure in pounds per square inch (psi), which we typically assume to be at an ideal level of 100 psi for calculations unless otherwise specified.

In this case, since the diameter is given as 2 inches, you will square the diameter:

[

d^2 = 2^2 = 4

Assuming the ideal nozzle pressure (NP) is 100 psi, you can substitute these values into the formula:

[

\text{gpm} = 29.7 \times 4 \times 100

]

Calculating this:

[

\text{gpm} = 29.7 \times 4 = 118.8

]

[

\text{gpm} = 118.8 \times 100 = 11880
