In order to effectively utilize fire hoses in firefighting operations, it is crucial to understand their water capacity. The water capacity of a fire hose determines the amount of water it can deliver to extinguish fires. This section will explain how to calculate the water capacity of a fire hose and highlight the factors that should be considered in this calculation.
## Explanation of how to calculate water capacity
Calculating the water capacity of a fire hose involves a simple formula. The first step is to find the cross-sectional area of the hose. For a 1 3/4″ fire hose, the diameter can be converted to inches, which amounts to 1.75 inches. To calculate the radius, we divide the diameter by 2, giving us a radius of 0.875 inches. The cross-sectional area can then be determined using the formula for the area of a circle: A = πr^2. By substituting the radius value, the cross-sectional area of a 1 3/4″ fire hose is approximately 2.396 square inches.
Next, we need to convert the area to square feet by dividing it by 144, since there are 144 square inches in a square foot. Therefore, the cross-sectional area of a 1 3/4″ fire hose is approximately 0.0166 square feet.
## Factors to consider in calculating capacity
While the formula explained above provides a general calculation for water capacity, there are a few important factors to consider that may affect the actual capacity of a fire hose. One such factor is the thickness of the hose’s walls, as it reduces the internal space available for water flow. The material of the hose can also impact its water capacity, as some materials may have higher friction losses and affect the flow rate.
