Questions and Answers

According to the National Board of Fire Under Writers Formula, what is the water demand for a central congested high valued city with population greater than 200,000?

$Q = 9100\, \text{lit/minute for first fire and } Q=36,400 \text{ to } 54600\, \text{lit/minute for a second fire}$

$Q = 36,400\, \text{lit/minute for first fire and } Q=54600 \text{ to } 9100\, \text{lit/minute for a second fire}$

$Q = 54600\, \text{lit/minute for first fire and } Q=9100 \text{ to } 36,400\, \text{lit/minute for a second fire}$ (correct)

$Q = 9100\, \text{lit/minute for first fire and } Q=54600 \text{ to } 36,400\, \text{lit/minute for a second fire}$

What is the formula for Kuichling’s Formula for water demand?

$Q = \text{Amount of water required in liters/minute} \div (P)^{1/2}$

$Q = \text{Amount of water required in liters/minute} - (P)^{1/2}$

$Q = \text{Amount of water required in liters/minute} + (P)^{1/2}$

$Q = \text{Amount of water required in liters/minute} \times (P)^{1/2}$ (correct)

In the Freeman Formula, what does the variable $P$ represent?

Amount of water required in liters/minute

Quality of water

Treatment of raw water

Population in thousand (correct)
