Thanks! Does conductance only apply when the vacuum pump is switched on? If I switch off the pump and just open the valve to let the flow in, is it the equations for viscous flow I need to use?

Hi, I have a tank of air which has been depressurized to 0.2bar (absolute) via a vacuum pump, where air can be let in from atmosphere through pipework controlled by a valve. What would be the equation I can use to determine the flow rate into the tank with time? As the flow rate is determined by...
