Ex13-2 Carry out the arithmetic checks for Reduction of level of Ex13-1.

Solution :

S B.S. = 11.720 m; S F.S. = 11.670 m

Therefore S B.S - S F.S. = 0.050 m

S Rise = 5.595 m; S Fall = 5.545 m

Therefore S Rise - S Fall = 0.050 m

Last R.L. - First R.L. = 150.535 - 150.485 = 0.050 m.

S B.S - S F.S. = S Rise - S Fall = Last R.L. - First R.L.
