Enter the volume of fluid processed and the time taken to process the fluid into the calculator to determine the hydraulic capacity. This calculator can also evaluate any of the variables given the others are known.

Hydraulic Capacity Formula

The following formula is used to calculate the hydraulic capacity.

HC = Q / t

Variables:

  • HC is the hydraulic capacity (GPM or LPM)
  • Q is the volume of fluid processed (gallons or liters)
  • t is the time taken to process the fluid (minutes)

To calculate the hydraulic capacity, divide the volume of fluid processed by the time taken to process the fluid. This will give you the hydraulic capacity in gallons per minute (GPM) or liters per minute (LPM), depending on the units used for the volume of fluid and time.

What is a Hydraulic Capacity?

Hydraulic capacity refers to the maximum amount of fluid a hydraulic system can handle or process within a specific period. It is a crucial factor in designing and operating hydraulic systems such as pumps, valves, and cylinders, as it determines the system’s efficiency and effectiveness in transmitting power. The hydraulic capacity is typically measured in gallons per minute (GPM) or liters per minute (LPM) and can be influenced by factors such as pressure, temperature, and fluid viscosity.

How to Calculate Hydraulic Capacity?

The following steps outline how to calculate the Hydraulic Capacity.


  1. First, determine the volume of fluid processed (Q) in gallons or liters.
  2. Next, determine the time taken to process the fluid (t) in minutes.
  3. Next, gather the formula from above = HC = Q / t.
  4. Finally, calculate the Hydraulic Capacity.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

volume of fluid processed (Q) = 150 gallons

time taken to process the fluid (t) = 30 minutes
