The Hose Capacity Calculator is a useful tool for determining the volume of liquid that a hose can hold. By inputting the hose's diameter and length, this calculator provides the total capacity in gallons, making it helpful for applications such as irrigation, firefighting, and other fluid transportation needs.
Historical Background
Understanding the capacity of hoses has been crucial in many fields, particularly in agriculture and firefighting, where precise fluid delivery is vital. Knowing the hose's capacity helps ensure that the right volume of water or other liquid is delivered to the needed area.
Calculation Formula
The capacity of a hose is calculated using the formula for the volume of a cylinder:
\[ \text{Volume (cubic feet)} = \pi \times r^2 \times \text{length (feet)} \] Where:
 \( r \) is the radius of the hose in feet (half of the diameter converted to feet).
To convert cubic feet to gallons: \[ \text{Capacity (gallons)} = \text{Volume (cubic feet)} \times 7.48052 \]
Example Calculation
For a hose with a diameter of 2 inches and a length of 50 feet:
 Convert diameter to feet: \( \frac{2}{12} = 0.1667 \, \text{feet}\).
 Radius: \( \frac{0.1667}{2} = 0.08335 \, \text{feet}\).
 Volume in cubic feet: \( \pi \times (0.08335)^2 \times 50 \approx 1.093 \, \text{cubic feet}\).
 Capacity in gallons: \( 1.093 \times 7.48052 \approx 8.18 \, \text{gallons}\).
Importance and Usage Scenarios
This tool is important for accurately measuring the fluid capacity of hoses in:
 Irrigation systems, ensuring the correct amount of water is delivered to crops.
 Firefighting, where determining the water capacity of hoses can be crucial for firefighting efficiency.
 Industrial fluid transport, where specific quantities of liquids are needed for various processes.
Common FAQs

Can this calculator be used for hoses with noncircular crosssections?
 No, this calculator is designed for hoses with circular crosssections. For noncircular hoses, different formulas would be required.

Does the material of the hose affect its capacity?
 No, the material does not affect the volume capacity, but it may influence the pressure the hose can handle.

How accurate is the capacity calculation?
 The accuracy depends on the precision of the input values (diameter and length). Make sure to measure accurately for the best results.
