tan2(45+π/2).
Where π=angle of friction.

Akhil said:   7 years ago
Active earth pressure = 1/(tan2 (45° + π/2)) = tan2 (45° + π/2)
ka = 1/ kp.

ka=1/tan^2(45°+Φ/2).
=tan^2(45°+Φ/2).
=flow value.

What will be for soil at rest?

Staffana aishwarya said:   7 years ago
Soil at rest K0 = 1 - sinΠ.

Mahesh said:   6 years ago
How to calculate the angle? Please, anyone, tell me.

Manoj said:   4 years ago
According to me, Pa is proportional to cot^2(45+π/2).
