Percolation Rate Formula

The following two example problems outline the steps and information needed to calculate the Percolation Rate.

PER = W / T
  • Where PER is the Percolation Rate (mL/min)
  • W is the amount of water (mL) 
  • T is the percolation time (min) 

To calculate a percolation rate, divide the amount of water by the percolation time.

How to Calculate Percolation Rate?

The following example problems outline how to calculate Percolation Rate.

Example Problem #1:

  1. First, determine the amount of water (mL).
    • The amount of water (mL) is given as: 500.
  2. Next, determine the percolation time (min).
    • The percolation time (min) is provided as: 10.
  3. Finally, calculate the Percolation Rate using the equation above: 

PER = W / T

The values provided above are inserted into the equation below and computed.

PER = 500 / 10 = 50.00 (mL/min)


Example Problem #2: 

For this problem, the variables required are provided below:

amount of water (mL) = 600

percolation time (min) = 60

Test your knowledge using the equation and check your answer with the calculator..

PER = W / T = ?
