Question

I need help on this question: This question is to see to validate or the two methods using a data set taken from the Rogers and Mayhew property tables.

The specific volume of saturated steam can be calculate using the ideal gas equation of state and the saturation temperature and pressure as follows,
RTa (P)
Og
=
where,
v, = specific volume of the saturated steam (units kg/m3)
P = Pressure (units Pa)
Tsat (P) = Saturation temperature at pressure P (units K)
R = specific ideal gas constant (=461.5 J/kg K for steam)
It is well known, however, that the ideal gas equation will produce very large errors at high pressure, in particular as the pressure approaches the critical point.
Affandi et al. (2013) have proposed an alternative equation of state, based on the reduced saturation temperature (T, = T/Terit) only, as follows,
In(v.) = a+ b[(1/T,)]04 + c/T; + d/T,4 + eľT;5
Values for a - e are given below
а
b
e
