Redlich–Kwong equation of state calculator

Calculate pressure/volume/temperature, compressibility factor, and fugacity coefficient for liquid/gas/fluid.
Warning: may return a value for a metastable state.

Usage:

Critical temperature = Temperature = °C K
Critical pressure = Pressure = Pa kPabaratmMPa
Molar volume = m³/mol dm³/mol cm³/mol

Results:
gas:n.a.
liquid:n.a.

Notation:
  T = temperature
  P = pressure
  Vm = molar volume
  Tc = critical temperature
  Pc = critical pressure
  reduced quantities: Tr=T/Tc, Pr=P/Pc, Vr=Vm/(R*Tc/Pc)
  Z = Pr*Vr/Tr= P*Vm/(R*T) = compressibility factor
  φ = fugacity coefficient
  atm = 101325 Pa
