Quantity of Water by National Board of Fire Underwriters Solution

STEP 0: Pre-Calculation Summary

Formula Used

Quantity of Water in Liters Per Minute = 4637*sqrt(Population in thousands)*(1-(0.01*sqrt(Population in thousands)))
Q = 4637*sqrt(P)*(1-(0.01*sqrt(P)))
This formula uses 1 Functions, 2 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Quantity of Water in Liters Per Minute - (Measured in Liter per minute) - The quantity of water in liters per minute is the amount of water required to extinguish a fire.
Population in thousands - The population in thousands is the number of people living in a fore broke area. It is usually taken in thousand like 20,000 is 20.

STEP 1: Convert Input(s) to Base Unit

Population in thousands: 14 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = 4637*sqrt(P)*(1-(0.01*sqrt(P))) --> 4637*sqrt(14)*(1-(0.01*sqrt(14)))

Evaluating ... ...

Q = 16700.8853024708

STEP 3: Convert Result to Output's Unit

0.278348088374513 Cubic Meter per Second -->16700.8853024708 Liter per minute (Check conversion here)

FINAL ANSWER

16700.8853024708 ≈ 16700.89 Liter per minute <-- Quantity of Water in Liters Per Minute

(Calculation completed in 00.004 seconds)
