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?? 🙏🙏🙏🙏
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.
how about instead of a manhole its Interceptor box and going to manhole? should also RD in IB?
Yes RD is actually hotizontal distance which is required for slope calculation
@@civillogy i see.. how bout the second manhole in the video sir? they both have same Invert elevation?, the inlet and outlet

Thanks baloch,keep watching
and share with your friends
What do you mean by RD
Reduce distance
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

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