Enter the bucket size (L) and the fill time (sec) into the Calculator. The calculator will evaluate the Tap Flow Rate. 

Tap Flow Rate Formula

TFR = BS / FT * 60


  • TFR is the Tap Flow Rate (L/min)
  • BS is the bucket size (L)
  • FT is the fill time (sec)

To calculate the Tap Flow Rate, divide the bucket size by the fill time in seconds, then multiply by 60.

How to Calculate Tap Flow Rate?

The following steps outline how to calculate the Tap Flow Rate.

  1. First, determine the bucket size (L). 
  2. Next, determine the fill time (sec). 
  3. Next, gather the formula from above = TFR = BS / FT * 60.
  4. Finally, calculate the Tap Flow Rate.
  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.

bucket size (L) = 4774

fill time (sec) = 123
