Silly me, I came all the way to Afghanistan and forgot to bring my CERM.
I'm writing up a request for a design/build proposal for a drainage system for one of the water treatment plants we're building over here. I know the flow of the waste water from the treatment plant is 4 liters/second, but they are also going to need to figure in the water coming out from the three storage tanks if they ever overflow or need to be drained. The only reference I can see in the specs is 16 L/s for overflow per tank, but that seems a little low for a 211k gallon tank with 3.5 meters of head and an 8-inch outlet. It's going to be piped, but I figured on just using the orifice calculation.
An answer would be great, but I'll also need the equation because I still have to check the actual valve to verify the size...can't get good afghan help. Thanks.
