The rate of percolation is defined as the amount of percolated water per unit of time.It measures the rate of movement of water through the soil.Given, Amount of water= 200 ml. Percolation time= 40 min. Rate of percolation= Amount of water(ml) / Percolation time(min) = 200ml /40ml = 5ml/min.Hence the rate of percolation is 5ml/min.
