Longitudinal Section Steps (sheet 3) [modified]

Post by amelsakka on Fri 02 Jan 2009, 7:45 am

I made simple steps to solve longitudinal section problems, I hope they are easily understandable.
Please feel free to ask about anything in the document:

http://rapidshare.com/files/178918838/Longitudinal_sheet3.pdf[url][/url]

I will solve the sheet itself on excel and will upload after Gom3a prayer inshaa Allah.
but I think you need to know the concept to understand the sheet solution without, as they will be just numbers allocated into tables !!

So good luck, and I really hope that I could explained the steps clearly in the document.


MODIFIED:
I modified the steps, because the Dr told me on phone today, that we can ignore some details, which is not required from us in tomorrow's exam.
http://rapidshare.com/files/179077367/Longitudinal_Basic.pdf

if anyone already studied the original steps above and feels that he will be confused, then ignore this modified file.
(They are both correct, but the modified one has less steps.)

Guys, very important notice:
Dr Yehia repeated that comment twice: All levels (whether G.L or I.L) should be written with the standard format:
(x.yy)

Brackets are mandatory and ONLY two digits (not less, not more) after the decimal separator.

(4) should not be written (4.00)
(10.232) should be written (10.23)

Sorry, there is an important step I forgot.
This is a general check, should be made whether in branch or main line.

When calculating I.L at every manhole,,, if this manhole suffered a change in diameter (the pipe before is smaller than the pipe after),, then after you get the I.L. Add another I.L to the manhole: I.L new = I.Lold - (D big - D small)
