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) 

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: 

The variables needed for this problem are provided below:

hose radius (in) = 3

hose length (in) = 1500

Entering these values and solving gives:

HV = 3.14159*3^2 * 1500 / 281 = 150.93
