Fluid Properties Fluid =
Critical pressure, Pc = bara
Vapour pressure, Pv = bara
Liquid density, r = kg/m³
Liquid viscosity, m = cP

Upstream pressure, P1 = bara
Downstream pressure, P2 = bara
Volumetric flowrate, Q = m³/h
Valve and Piping Data
Line number =
Initial valve Cv =
Nominal inlet valve size, d = inch
Internal diameter upstream reducer, D1 = inch
Nominal outlet valve size, d = inch
Internal diameter downstream expander, D2 = inch
Pressure recovery factor for valve, FL = -
Pressure recovery factor for valve, FL = -
FL value to be used =
Pressure differential at non-choked conditions = bar
Pressure differential at choked conditions = bar
Flow through valve is = -
P re ssur e d if fe rent ial use d f or siz ing = b ar
