1 in 20 means 0.05,
So in 30 means 0.05*30=1.5(which is h),
And we know the formula for a lope correction =h^2/2L,
So 1.5^2/2*30=0.0375m and in cm.
We get 3.75 m.

Slop correction Formula = h^2/2*L.
h = 30*(1/20) = 1.5
Hence, correction = 3.375 cm.
h = 30*(1/20) = 1.5
Hence, correction = 3.375 cm.

Here, l= 30 m.
Gradient= 1 in 20, i.e h= 30/20= 1.5
We know, slope correction (Ch)= - h^2/2l
= - (1.5)^2/(2*30) m.
= -3.75 cm.
Gradient= 1 in 20, i.e h= 30/20= 1.5
We know, slope correction (Ch)= - h^2/2l
= - (1.5)^2/(2*30) m.
= -3.75 cm.

How h= 1.5?

30 m length, h = 1.5.
Given gradient is 1 in 20 i.e 1/20.
The equation of slope correction is,
= h^2/2l.
= 1.5^2 / 2*30 m,
= 2.25 / 60m,
= 0.0375 m or 3.75 cm.
Given gradient is 1 in 20 i.e 1/20.
The equation of slope correction is,
= h^2/2l.
= 1.5^2 / 2*30 m,
= 2.25 / 60m,
= 0.0375 m or 3.75 cm.
