Tables of Thermodynamic Properties by Dr. M. A. Habib Professor, Mechanical Engineering Department, KFUPM. Procedure. The procedure of calculating the thermodynamic property is as follows: Define the state by two independent properties. Choose SI units tables.
The procedure of calculating the thermodynamic property is as follows:
Since the pressure and temperature are two dependent properties inside the saturation region, therefore, this state is not inside the saturation region
The state is not inside the saturation region
T, oC P, kPa vf, m3/kgvfg, m3/kg
100 101.3 0.001044 1.67185
105 120.8 0.001047 1.41831
Thus, P102 =109.1 kPa
Thus T= 98.55oC
Thus v= 0.247 m3/kg
From saturation tables, determine vf and vg at T. The region is determined based on the following conditional table:
Given P, v
Water given at 100kPa and 40 oC
Thus, from this table, T= Tsat = -22.58 oC and
Substituting for h=467 kJ/kg gives P=2259.1 kPa.
Substituting for h=3000 kJ/kg gives T=276.4 oC
