Need Help Calculating HGL/EGL of storm drain system by hand 2

[Kendalljazz]

I designed storm drain system in civil 3d and I want to calculate hgl and egl by hand. Does anyone have a good resource I can read our watch that goes step by step on how to calculate these by hand. I am still insure about how standard step method works, and why we need it to calculate hgl.

If you still have your fluid mechanics text book, it probably has a good explanation.

We didn't use textbooks when I was in college. I was hoping someone on here had a website that had hgl calculations done by hand.

Sorry, my gray hair is showing again. A quick google search offers several options.

--Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."

FHWA Hydraulic Engineering Circular No. 22 has a good guide with examples:
