View ArticleForum Post: Negative Pressures in Pipe
My model consists of a reservoir from a higher elevation supplying water to two tanks at a lower elevation. The pipe leading to the tanks keeps going to a negative pressure despite the inclusion of air...

The correction depends on why you have having negative pressure. If it is because the pipes are at a higher elevation than the surrounding tanks, you may need to pump over that high point. If it is...

The order of elevation is as follows: Reservoir > Pipe > Tank so I don't think I need to pump. In terms of head loss, I'm only pushing less than 2MGD through an 8-inch pipe. It would seem...

I looked at the model and animated the profile. At times the flow to the lower tanks is so great that the HGL drops below the ground. This is an elevation problem. The HGL at the reservoir is at...

I agree that the reservoir HGL is too low. I'll have to check on that. However, are the high flows to the tank realistic?

Once again, you have several options. 1. The tanks are too low relative to the source. They will fill and either overflow or if you have a altitude valve, shut off. Raise the top of the tanks so you...

Hello all. I am carrying out an optimization run using darwin designer.I am just curious to know if there is a way you could use the tank size(Volume) as a decision variable in addition to the pipe...
View ArticleForum Post: RE: Darwin designer options
Tank volume sizing is an entirely different problem from pipe sizing and doesn't fit into the GA. There are multiple tank purposes and you would need to simulate a variety of EPS runs for fires and...

Hello Bushra, It appears that the issue is related to the pumps pumping against a tank that is full. The pump status is still on, but this the pump is full (and there is no demand in the system), that...
