reading.
H.I=R.L of B.M+B.S
H.I=50 m+1.25 m=51.25 m
R.L of Forward Station=H.I−F.S
R.L of Forward Station=51.25m−1.85m=49.4

reading. H.I=R.L of B.M+B.S H.I=50 m+1.25 m=51.25 m R.L of Forward Station=H.I−F.S R.L of Forward Station=51.25m−1.85m=49.4
thank you bro
H.I=R.L of B.M+B.S
H.I=50 m+1.25 m=51.25 m
R.L of Forward Station=H.I−F.S
R.L of Forward Station=51.25m−1.85m=49.4
