Calculating Mass Flow Rate of Steam Turbine

AI Thread Summary
To calculate the mass flow rate of steam in a turbine operating at 3 MPa and 450°C, expanding adiabatically to 10 kPa with a power output of 800 kW, the correct method involves applying the first law of thermodynamics and relevant equations for steam properties. Users confirmed that the approach taken in the calculations was correct, although specific numerical values were not verified. Additionally, a participant inquired about applying similar equations for an Organic Rankine Cycle (ORC) turbine using R-134a refrigerant, indicating interest in the versatility of the methods discussed. Overall, the discussion emphasizes the importance of verifying calculations and understanding thermodynamic principles for different working fluids. Accurate mass flow rate calculations are crucial for effective turbine design and operation.

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

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
