Hi Their
I discussed my colleague about the minimum water level for submersible pump when it equipped with water jacket;
My friend said when you use water jacket for the submersible pump you can reduce the required minimum water level so you can operate the pump at dry operation.
I replied that...
Hello their
I'm working on a ground reservoir with a volume 4000m3 , In let pipe is 300mm ( 2 pipes ) , is there any design criteria regarding the sizing of the pipe size of the washout and the over flow pipe? or rule of thump?

We use Airlift pump , pipes with Air Compressor , to remove the settled sands in waste treatment plant at the head work (inlet) ,
How we can calculate the compressor capacity ? is the friction losses for the flow ( air + water + sand )considered as same ass the water flow friction losses?

Hallow Their,
It is known that the pump doesn't create pressure but flow against pressure.
The operation point of the pump will move along its performance curve according to the pressure ahead the pump ; static and frictions
Now , How the residual pressure is created? If we need 1 bar at the...
