Second order modelling 6 - two tank systems

Shows how different arrangments of two tanks leads to models with different characteristics. Indicates the need for more involved modelling approaches to deal with complex systems.
Lectures aimed at engineering undergraduates. Presentation focuses on understanding key prinicples, processes and problem solving rather than mathematical rigour.

very few people discussed dynamics of fluid systems on UA-cam, thanks Rossiter.

this is awesome......thank you.....u good

[@erickmagalhaes1244]

What about two tank system in which the first tank outflow is controlled by a pump, making Q1 out constant?

[@Nelsona300]

hi Anthony, i am currently modelling a coupled tank but without the second inflow, fin2, would this be the same as for the tank example previous to the coupled tank or would it be different?

[@johnrossiter2323]

The main thing is to do a volume balance. Total In flow - total out flow = rate of change of stored volume.Anthony

[@aarsh0608]

Sir, in the case where the tanks are coupled in parallel, isn't the flow rate f12 of the form R12*sqrt(h1-h2) instead of R12*(h1-h2)? Kindly explain.

Thanks dr. (y)

[@mohammedkayed6253]

I confused about f12=R12(h1) and flow=R(P1-P2)

[@johnrossiter2323]

Flow rate is (locally) proportional to the difference in pressure across a pipe (or plug hole or similar). As pressure is proportional to depth one can change the constant and use depth instead of pressure.Anthony

[@sevajuneva]

John Rossiter flow is proportional with pressure drop it means

what about a large flow which happen in real, how do u model that
