Question

Answer b) only

a) Steam is one of the important utility in the process industry which is utilized in many applications.
It is desired to compress the steam from 100 kPa to 5000 kPa isothermally at 500 °C. During this
process the thermodynamic properties of steam might change. If steam behaves ideally at its initial
conditions, estimate the fugacity of the steam during this compression process.
b) At the same temperature of the following data is calculated;
P (MPa)
î (m³/ kg)
0.8
0.3241
1.0
0.2579
1.2
0.2138
i.
Estimate the isothermal compressibility (k) for saturated steam at 1 MPa.
