Why would flow rate through a regulator increase steadily?
Why would flow rate through a regulator increase steadily?
(OP)
I am trying to make sense of the way my Swagelok RSH10 pressure regulator behaves. Its inlet is connected to a bank of 10 parallely connected nitrogen gas cylinders each at 150 bar. As the inlet pressure decreases, for a set outlet pressure of 10 bar, the flow rate steadily increases at a rate of about 100 Nm3/hr (Normal meter cube per hour) per minute.
I am aware of the "dependency" phenomenon in regulators where the outlet pressure increases with decrease in inlet pressure. Why is the effect so profound?

The flow is directed towards a nozzle where the flow is supposed to be choked. But this trend has left me confused.
