Question

What is the porosity of the gravel sample?(The sediment volume for each sample is 400ml.)

Answer 1

28.75 %

Step-by-step explanation:

porosity is the term which is defined as the volume of voids present in the soil to the total volume of the soil.

it is denote by n where
`n = (V_v)/(V)`

A porous material is one which contain pores, if a material is porous it will allow the water to pass through it.

the porosity of the gravel sample is 28.75%

Answer 2

Answer: The correct answer is : 25.50%

Explanation: Porosity, n = Vv / V * 100

It is the value of the volume of fords as a percentage of the total volume of the sample. For the value of the porosity, the air or water in the pores is not taken into account. The porosity of the gravel sample is 25.50%
