Enter the initial fluid volume, loss rate, and time into the calculator to determine the remaining fluid volume. This calculator helps estimate the fluid volume that will remain after a certain period due to a consistent loss rate.

Fluid Loss Formula

The following formula is used to calculate the remaining fluid volume after a certain time period.

RV = IV - (LR * T)

Variables:

  • RV is the remaining fluid volume (gallons)
  • IV is the initial fluid volume (gallons)
  • LR is the loss rate (gallons per hour)
  • T is the time (hours)

To calculate the remaining fluid volume, subtract the product of the loss rate and time from the initial fluid volume.

What is Fluid Loss?

Fluid loss refers to the volume of fluid that is lost from a system over time due to leaks, evaporation, or other forms of depletion. It is a critical factor in various industries such as hydraulic systems, cooling systems, and medical fluid management. Understanding and calculating fluid loss is essential for maintaining system efficiency, preventing damage, and ensuring safety.

How to Calculate Fluid Loss?

The following steps outline how to calculate the remaining fluid volume after fluid loss.


  1. First, determine the initial fluid volume (IV) in gallons.
  2. Next, determine the loss rate (LR) in gallons per hour.
  3. Next, determine the time (T) in hours over which the fluid is lost.
  4. Next, gather the formula from above = RV = IV – (LR * T).
  5. Finally, calculate the remaining fluid volume (RV) in gallons.
  6. 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.

Initial fluid volume (IV) = 100 gallons

Loss rate (LR) = 5 gallons per hour

Time (T) = 3 hours
