The percolation rate for soil samples are:

3.
Calculate the percolation rate for each soil sample by using the following formula
For example, if a sample took 23 min for percolation of 40 ml water, then
Volume of percolated water will be less than the volume taken initially, as some of the water will be
absorbed by the soil.)

Answer 1

Answer:

Given,

Amount of water = 200 mL

Percolation time = 40min

Rate of percolation = Amount of water in mL / Percolation time in min

=200 / 40

=5 mL/min.

Hence, the rate of percolation of water through the given soil sample is 5 mL/min.
