Design of Surge Tank

[hedcor]

We are currently designing a 16.4MW hydro electric power plant with gross head of 295m, Qd=7.27cms, pipe dia = 1.3m which involes wier, conveyance line, surge tank, penstock line and power plant. I need some advice and reference/spreadsheet in designing a surge tank especially the height.

Thanks

With a gross head of over 900 feet, do you have a place to position the surge tank for the static head, let alone the runup after the butterfly valves are closed? Runup is likely to be 50 to 100 feet.

I did one about 35 years ago for a local hydroelectric company and, if memory serves me right, we used some design information from the Corps of Engineers.

That was before the age of spreadsheets...

yup position is based on the static head.. do you still have a copy of the reference. thanks

mr. mike how did you calculate the runup..any basic calculations..thanks

Unfortunately not being 35+ years ago. Best bet is to research COE design material. It does exist. Sorry I cannot be of more help.
