Quantity of Water by Freeman's Formula Solution

STEP 0: Pre-Calculation Summary

Formula Used

Quantity of Water in Liters Per Minute = 1136*((Population in thousands/5)+10)
Q = 1136*((P/5)+10)
This formula uses 2 Variables

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 = 1136*((P/5)+10) --> 1136*((14/5)+10)
