Hi LittleInch, there is not any seconday pressure gauge to meassure the drop over the filter. The idea is to use the tranducer at the bottom of the tank to meassure the increase in pressure from the pump. As i understand from the posts above, it will see P = W_max + delta_F_max, delta_F_max...

Hi all, Thanks for the great discussion, just to clarify what this is used for: This is a bio filter with biomedia in the red area, this area will get gunked up with all kinds of stuff during operations over time. The whole idea here is that there is a constant volume pumping through it all...

Hi LittleInch, Thanks for the quick reply. The pressure trancducer is used to meassure the water level in the tank, but inspite of my recommendations they also want it to control the pump. Thanks again.

Hi, I am trying to understand what a certian pressure at the bottom of a tank would be. I have attached a drawing trying to sketch the problem. The pump is pumping water in at at the bottom with a fixed volume/hr and pressure . The water then travels through some biomedia which results in a...

Thank you all for your answers!

Hi @Compositepro, The purpose is aquaculture, the tank with the green pipe will maintain the level in several other tanks and only have one retun pipe to the filtration system, the pipes in tank 2 can be lowered/raised. For the purpose of keeping things simple i did not mention it. I have no...

@LittleInch Thanks for your answers and time. Just to understand you correctly, you are advicing to ioncrease the pipe size towards the outlet just to reduce the flow velocity, correct? Thanks again!

Hi @LittleInch, So the maximum differential head between top of liquid in tank 1 and exit from the pipe in tank 2 is 0.5m - Yes that is correct, the maximum water rise in tank 1 must be 0.5 m. what will be more difficult though is working out what happens in tank 2. not really sure what you...

Hi all, I have a small problem i would like your help with. I am more interested in how to do the calculation so i can do it in the future than the solution itself :) I have two tanks, different volumes but both six meters high and I want to dimension the pipe between the two tanks. see the...
