Razia conducted an experiment related to percolation rate. It took 40 min for 200 mL of water to percolate through the soil sample. Calculate the rate of percolation. [2 marks]

Open in App

Solution

Percolation rate = Amount of water passed(mL)/ Time taken (min) [1 mark]

The amount of water passed is 200 mL and the time taken for it to pass through the soil is 40 minutes. We can substitute these values in the formula to get the value for percolation rate.

The correct answer in 5mL/min. [1 mark]
