150/ n^2 because 30 metre chain used and now slope current is 150/ 20^2 = 150 ÷ 400 = 0.375 m or 3. 75 cm.

Slope correction = h^2 / 2l.
h = 20/30 = 1.5.
l = length.
By submitting the value you will get the answer.
h = 20/30 = 1.5.
l = length.
By submitting the value you will get the answer.

h^2/2L.
h= 1.5 (because of 1:20, 1/20 * 30 = 1.5),
h= 2.25/60,
h= 0.375m,
h= 0.375 * 100,
h= 3.75cm.
h= 1.5 (because of 1:20, 1/20 * 30 = 1.5),

h= 0.375 * 100,
h= 3.75cm.

For Determining H = 20/30 = 1.5
The formula for slope H^2/2L.
L = 30.
1.5^2/2×30 = 0.0375 × 100 = 3.75cm.
The formula for slope H^2/2L.
L = 30.
1.5^2/2×30 = 0.0375 × 100 = 3.75cm.

But 30 M is along the gradient, not horizontal distance.
So, the value of h won't be exactly 1.5 M.
So, the value of h won't be exactly 1.5 M.

By using of similarity of the triangle.
H = 30÷401 and putting into slope correction formula.
H = 30÷401 and putting into slope correction formula.

Slope correction for a sloping ground = h^2/2l.
Where h = height.
l = length of the ground.
Where h = height.
l = length of the ground.

(1.5)2 / 2x3000 = 3.75 cm.
Note: Length 30 m, gradient 1/20 ; h= 1.5.
Equation : h2/2l.
Note: Length 30 m, gradient 1/20 ; h= 1.5.
Equation : h2/2l.

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.
