Pressure drop across valve
Pressure drop across valve
(OP)
If a high pressure system ( say 9 barg ) with high flow ( say 2000kg/Hr ) is discharging into atmosphere through a 2" gate valve and a small length of pipe ( Small friction drop ).
Will the pressure drop take place across the valve or the flow will choke at the end of the pipe.
Thanks

RE: Pressure drop across valve
But if it is required to maintain a certain low back pressure on the valve outlet ( say 0.1 barg ). Is it possible to achieve that.
Actually this is a requirement from a depressurizing system where vendor has specified low back pressure for the vent valve.
I am not able to imagine how this can be achieved if choking will take place at the exit ( therefore there will be high back pressure at the valve outlet. )
Thanks
