What is the best way to calculate valve leak-by rate in a angle control valve? The data that is available to me is upstream pressure at different valve positions, downstream pressure, upstream temperature, and the information on the valve, such as Cv and other technical stuff.
I am trying to...
I have a problem a flowrate that I am trying to estimate without the use of a metering device.
The setup that I am dealing with involves an upstream gate valve that isolates the downstream control valve (Valtek angle valve) that vents to atmosphere. These two valves are in service with 660#...
