Assertion (A): In Mollier chart for steam, the constant pressure lines are straight lines in the wet region.
Reason (R): The slope of constant pressure lines in the wet region is equal to T.
Explanation:
- The Mollier chart, also known as the steam table or enthalpy-entropy diagram, is a graphical representation of the thermodynamic properties of steam.
- It is widely used in the field of thermodynamics and is particularly useful for engineers working with steam power plants, refrigeration systems, and other applications involving steam.
- The chart shows the relationship between enthalpy (h), entropy (s), temperature (T), and specific volume (v) for various states of steam.
- In the wet region of the Mollier chart, where the steam is a mixture of vapor and liquid, the constant pressure lines are indeed straight lines.
- This is because the enthalpy of the mixture remains constant along these lines.
- The slope of the constant pressure lines in the wet region represents the rate of change of temperature with respect to specific volume, and this slope is equal to T.
- The reason for this is that the temperature of the mixture is directly related to its enthalpy and specific volume.
- As the specific volume increases, the enthalpy of the mixture remains constant, resulting in a decrease in temperature.
- Similarly, as the specific volume decreases, the enthalpy remains constant, resulting in an increase in temperature.
- Therefore, the slope of the constant pressure lines in the wet region is equal to T, which represents the rate of change of temperature with respect to specific volume.
Conclusion:
- Both the assertion (A) and the reason (R) are individually true.
- The reason (R) is the correct explanation of the assertion (A).
- Hence, option 'A' is the correct answer.
Reason (R): The slope of constant pressure lines in the wet region is equal to T.
