Hypothesis and equations
Generic flow control model for a secondary hydraulic circuit including a pump.

Instructions for use
The input x, between 0 and 1, diverts the flow via 3-way velva. When x is greater than 0.5, it means that the secondary circuit emits too much heat and therefore the sound flow must bereduced. x:=1: no flow in the secondary circuit, everything is redirected to the secondary circuit. x=0: all the flow fixed to the pump is sent to the secondary circuit.
The pump is an all or nothing system which stops when there is no need in the secondary circuit (when x=1.)
