I finally know where the h2s came from. Thank you very much!

Congratulation for solving well this problem
Much respect from TANZANIA 🇹🇿🇹🇿

Why are the actual and isentropic pressures the same?

[Jack-nvto]

Thank you for this wonderful course. Quick question: I think we should not use the actual Work (2000KW) to get actual flow rate. Should use Isentropic Work.

Dear Doctor,
why S1 was equal to S2s and not S2a?

[yolo]

in problem one, why do we keep the pressures the same for the isentropic process? Couldnt we keep the tempratures the same instead?

[kylecatman]

If it's reversible ONLY does that mean S2 - S1 = Q/T ?? Because Sgen would be zero at that point.

back here helping me review for thermo 2

[saravmohan]

why turbine work output is negative it should be positive since work done by the system is positive while work done on the system for compressor is negative right???

Same problem but 2.5 Mpa and 450°C at inlet, and 60kpa and 100°C at outlet pls 🥲 I can't calculate the value of h2 in the tables
