Question

A soil sample took 20 minutes for 400 ml of water to percolate. Calculate the rate of percolation.​

Answer 1

Answer:

Explanation:

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.

Answer 2

Given,

Time taken by water to percolate = 20 minutes

Amount of water percolated = 400 ml

To Find,

The rate of percolation.

Solution,

Percolation is the movement and filtering of fluids through porous materials.

The formula for calculating the rate of percolation is

Rate of percolation = Amount of water percolated( in ml)/Time taken(in min.)

In this case

Amount of water percolated = 400 ml

Time taken = 20 minutes

Rate of percolation = 400/20 = 20 ml/min.

Hence, the Rate of percolation is 20 ml/min.
