Hello there,
I need to design a restriction orifice on a manual vent to atmosphere -
Vent Line Size DN50
Main Line Size DN300
Fluid - Natural Gas - dehydrated
P - Inlet = 15000 KPag
Temperature = 24 DegC
I have calculated the orifice diameter for critical flow condition, it came out to be a 7 mm hole. however, I don't know how to select the rest of the sizing. For example the material of orifice or is there any standard size which i can select and order??
thanks and regards,
