Period of Occurrence of Fire given Quantity of Water Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time period = ((Quantity of Water*(((Time Duration/60)+12)^(0.757))/4360)^(1/0.275))*31556952
T = ((Q_w*(((t_d/60)+12)^(0.757))/4360)^(1/0.275))*31556952
This formula uses 3 Variables

Variables Used

Time period - (Measured in Second) - Time period is the time period of occurrence of fire .
Quantity of Water - (Measured in Liter per minute) - The Quantity of Water is the amount of water required to extinguish a fire. It is the discharge in liters per minute.
Time Duration - (Measured in Second) - Time Duration is the time duration of fire.

STEP 1: Convert Input(s) to Base Unit

Quantity of Water: 759.265 Liter per minute --> 759.265 Liter per minute No Conversion Required
Time Duration: 3 Minute --> 180 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T = ((Q_w*(((t_d/60)+12)^(0.757))/4360)^(1/0.275))*31556952 --> ((759.265*(((180/60)+12)^(0.757))/4360)^(1/0.275))*31556952

Evaluating ... ...

T = 94670562.2029695

STEP 3: Convert Result to Output's Unit

94670562.2029695 Second -->2.99999068994273 Year (Check conversion here)

FINAL ANSWER

2.99999068994273 ≈ 2.999991 Year <-- Time period

(Calculation completed in 00.004 seconds)

Quantity of Water by National Board of Fire Underwriters

Go Quantity of Water in Liters Per Minute = 4637*sqrt(Population in thousands)*(1-(0.01*sqrt(Population in thousands)))

Period of Occurrence of Fire given Quantity of Water

Go Time period = ((Quantity of Water*(((Time Duration/60)+12)^(0.757))/4360)^(1/0.275))*31556952

Quantity of Water given Duration of Fire

Go Quantity of Water = (4360*(Time period/31556952)^(0.275))/(((Time Duration/60)+12)^(0.757))

Quantity of Water by Buston's Formula

Go Quantity of Water in Liters Per Minute = (5663*sqrt(Population in thousands))

Quantity of Water by Kuichling's Formula

Go Quantity of Water in Liters Per Minute = 3182*sqrt(Population in thousands)

Number of Simultaneous Fire Stream

Go Number of Fire streams = 2.8*sqrt(Population in thousands)

Population by Freeman's Formula given Quantity of Water

Go Population in thousands = 5*((Quantity of Water in Liters Per Minute/1136)-10)

Quantity of Water by Freeman's Formula

Go Quantity of Water in Liters Per Minute = 1136*((Population in thousands/5)+10)

Population by Kuichling's Formula given Quantity of Water

Go Population in thousands = (Quantity of Water in Liters Per Minute/3182)^2

Population by Buston's Formula given Quantity of Water

Go Population in thousands = (Quantity of Water in Liters Per Minute/5663)^2

Population given Number of Simultaneous Fire Stream

Go Population in thousands = (Number of Fire streams/2.8)^2

Period of Occurrence of Fire given Quantity of Water Formula

Time period = ((Quantity of Water*(((Time Duration/60)+12)^(0.757))/4360)^(1/0.275))*31556952
T = ((Q_w*(((t_d/60)+12)^(0.757))/4360)^(1/0.275))*31556952

What is Fire Demand ?

Fire demand is the amount of water required to extinguish fire.The water required for fire fighting in a given area. Although the actual amount of water used in a year is small for fire fighting. But the rate of use is large.
