Question

A certain sample of soil is used for testing the percolation rate. The amount of water taken is 400 ml and the percolation time measured is 10 mins. What is the percolation rate?

• A. 40 mL
• B. 40 mL/min
• C. 20 mL/min
• D. 20 min

Answer 1

The correct option is B

40 mL/min

The percolation rate (mL/min) is calculated by the formula = $\frac{\text{Amount of water (mL)}}{\text{percolation time (mins)}}$
Percolation rate = $\frac{400}{10}$
= 40 mL/min
