Porosity is inversely proportional of permeability.

That is porosity of clay >silt >sand > gravel.

Where as permeability is gravel >sand >silt> clay.

Water easily pass through sand, but not incase of clay. So how option A is right?

How many type of cement used in construction?

How can clay be more porous as compared to sand?

Chintu said:   10 years ago
Guys porosity is the water bearing capacity.

Clay can hold more water than sand.

Vicky said:   1 decade ago
D correct.

Porosity - % age of availability of pores.

Permeability - % age of water flow through it.

In sand - Pores % age are less, so we are not compacted.

In soil - Pores % age are more, so we are compacted mechanical mean.

Simple.

Question is wrong. It need to be corrected, because clay will never be porous than sand.

Nitesh said:   1 decade ago
Porosity is measure that tells you how much water can be retained in a soil while permeability is measure of ease with which water can pass through. So clay is more porous.

The particle size range for sand as per IS soil classification?

Sravya said:   1 decade ago
Yes, the clay has less porous than sand.
