1. The document provides a comparative chart of thermodynamic properties and analysis of different steam power cycles including reheat, regenerative, and reheat-regenerative cycles. It includes values at different state points, heat added and rejected, turbine work, pump work, thermal efficiency, and steam rate. 2. It asks questions about which state points show changes in values, what contributes to increases or decreases, if computed values are enough to calculate performances, if the geothermal cycle is different, and to show TS diagrams and observations of the cycles for power plant generation.

COMPARATIVE CHARTS FOR STEAM POWER CYCLES
JUST A REMINDER …… Can I now identify the concepts of the following:

 What is a Reheat, Reheat- Regenerative & Reheat-Regenerative Cycles?


 If geothermal power plant is included, will the process & values of thermodynamics at the TS
diagram different from the other cycle?
 How can relate the values from the comparative tables when preferred to be used as a steam
power cycle for the Power Generating Plant?
 If you are now ready, fill the value/s corresponding to the description in the comparative table
below based from the computed values for the analysis of other steam power cycles for steam
power generating plant?

QUESTIONS: Write your answer below the questions & upload your answer in your individual goggle shared drive.

1. Based from the comparative charts with values at different state points and analysis of the steam power cycle, answer the following:
a. Which of the state points show changes in the values?

b. What contribute to the increase or decrease, or change in such specific thermodynamic properties?

2. If given an opportunity to calculate the performance of the steam generator and prime movers such as steam turbine & steam engine,
are computed values enough to compute such performances? Justify your answer.

3. Is the cycle for the geothermal power plant generation different from the above mentioned cycles? Explain.

4. Show the TS diagram of the different cycles for geothermal, rankine, reheat, regenerative & reheat-regenerative cycles.

5. Based from the cycle, write your observations or reactions for such cycle that will bbe used for a “ Power Plant Generation System”.
