Calculating Mass Flow Rate of Steam Turbine

Click For Summary

Homework Help Overview

The discussion revolves around calculating the mass flow rate of steam in a turbine operating under specific conditions, including pressure and temperature changes during a reversible adiabatic process. The context is related to thermodynamics and fluid mechanics, particularly in the analysis of turbine performance.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to verify their calculation method for mass flow rate based on given turbine parameters. Some participants affirm the correctness of the method without checking the specific numbers. Another participant questions the applicability of the same equation for a different type of turbine using a refrigerant gas.

Discussion Status

The discussion is active, with some participants providing positive feedback on the method used by the original poster. However, there is no explicit consensus on the correctness of the numerical answer, and additional inquiries about related applications are being explored.

Contextual Notes

The original poster expresses concern about preparing for an upcoming test and seeks validation of their approach. There is mention of a different project involving an ORC turbine and the use of refrigerant, indicating potential variations in the application of the discussed principles.

Steam enters a turbine at 3 mpa and 450 c, expands in a reversible adaibatic process, (KE and PE are negligible) and exhausts at 10 kpa. The power output of the turbine is 800 kW. What is the mass flow rate?

I did the problem but I don't know if the anwser is correct and wanted to check because we have a test next week so I don't want to practice doing this the problem the wrong way all weekend.

Thanks

I didn't check the numbers, but your method of solving is very correct. Well done! :approve:
 
Thanks Siddharth
 
Dear jsbeckton i have also seen the equation i am working on orc turbine can i apply this equation for calculation with 134a refregrent gas in my project
