Enter the hose radius (in) and the hose length (in) into the Hose Volume Calculator. The calculator will evaluate and display the Hose Volume.

## Hose Volume Formula

The following formula is used to calculate the Hose Volume.

HV = 3.14159*HR^2 * HL / 281
• Where HV is the Hose Volume (gallons)
• HR is the hose radius (in)
• HL is the hose length (in)

To calculate the hose volume, multiply pi by the radius squared, then again by the length, and finally, divide by 281.

## How to Calculate Hose Volume?

The following example problems outline how to calculate Hose Volume.

Example Problem #1:

1. First, determine the hose radius (in).
1. The hose radius (in) is given as: 2.5.
2. Next, determine the hose length (in).
1. The hose length (in) is provided as: 500.
3. Finally, calculate the Hose Volume using the equation above:

HV = 3.14159*HR^2 * HL / 281

The values given above are inserted into the equation below:

HV = 3.15159*2.5^2*500/281 = 35.0488 (gallons)

Example Problem #2:
