2. Steam Tables and Mollier Chart

Ques: Estimate the SPECIFIC ENTHALPY, SPECIFIC ENTROPY and SPECIFIC VOLUME for the state of
Steam at 100 bar and 550°C present in a Boiler Drum. Use the Mollier Diagram.

Given Data:

p = 10MPa
T = 550°C
y

Pressure of Steam, p = 100bar
Superheated Temperature of Steam,
T=550°C

3. Since the state of Steam lies in the Superheated Region, so the Value of Specific Enthalpy,
Specific Entropy and Specific Volume can be obtained from the Mollier Chart directly.

There is no need to use any Formula.
Specific Enthalpy of the Steam- From the Mollier Chart
Specific Entropy of the Steam- From the Mollier Chart

Specific Volume of the Steam- From the Mollier Chart

4. Mollier-h, s Diagram
for Wer Steam

Referring the Mollier Chart, the Vertical Coordinate
of Point A will give the Specific Enthalpy of the
Steam.

Thus, Specific Enthalpy of the Steam is-

ha = 3500.9 kJ/kg

D = Sn avec A
entropy in lag K)

5. Specific Entropy of the Steam

Referring the Mollier Chart, the Horizontal Coordinate of Point A will give the Specific Entropy of the Steam.
Thus, Specific Entropy of the Steam is-

S = 6.7561 kJ/kg.K

Specific Volume of the Steam

Referring the Mollier Chart, the Curve passing through Point A having a Steeper Slope than the Pressure Lines, will give

the Specific Volume of the Steam.

Thus, Specific Volume of the Steam is-

03564m3/kg
