Great video. One question can we use the isentropic relation with constant specific heat gamme from compressible flow---> T2/T1=(p2/p1) ^(gamma-1)/gamma
I know that this might be late but yes you can actually calculate it. Assuming that ideal gas gamma for air is 1.4. you can find the temperature at isentropic condition, then proceed to computation for entropy using integral of Cp/R dT where values for Cp/R can be found at literatures.
learned more in this 6 minute video than the past two weeks of my class, thank you sir!
This was exactly what I needed.

what if W/m is not given?
table A-22 is ideal gas properties of hydrogen ...
he meant table A-21
not for my book
@@jackshea6787 man you sent me to 3 years back 😂 I graduated and got a job too :p
is it the same just using the entropy value at state one and using the same pressure for state 2 actual and interpolating a isen state 2 enthalpy?

Hey, nice vid! I was wondering, why does Isentropic Efficiency change with turbine load?
very helpful
