What do you mean by RD

[@civillogy]

Reduce distance

[@anti-poverty3103]

A map has a scale of 1:200. An existing sewer at point A is to be continued to point B and the
map distance between these two points is 16 cm. If the existing invert level at A is 50.20m and
B is at a falling gradient of 1 in 40, calculate:
i.
the invert level of point B.
ii.
the FS reading that the engineer should read in order to set out point B if an HPC
of 51.00m has been established
Can you please assist me?? 🙏🙏🙏🙏

[@civillogy]

yes sure.
But your question is not clear,if the distance between point A & B ia 16 cm then there will no much difference between their levels.
anyhow it will be 50.2-(0.025x0.16)=50.196m=invert level at B.
ii. FS depends on your HI.

@@civillogy please i was given Falling Gradient why don't you used it in the solution?
