cylinder. If the final volume of water left in the measuring cylinder is 50 mL
Find the percentage of water absorbed by the soil.

Answer 1

Answer:

these are examples understand see and solve

Explanation:

1.

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.
