Q.8 Razia conducted an experiment in the field related to the rate of percolation. She observed that it took 40 min for 200 mL of water to percolate through the soil sample. Calculate the rate of percolation.

Amount of water = 200 ml

Percolation time = 40 minutes

\(\therefore \) Percolation rate =\(\frac{amount of water}{percolation time} \)

= \(\frac{200ml}{40min} \) = 5 ml/min

Therefore, rate of percolation is 5 ml/min
