So I think I found the enthalpy value, assuming constant entropy, which worked out to be around 2217.17 kJ/kg. I had to find quality under constant entropy first in order to do so. Consequently, I also found the isentropic turbine efficiency to be around 91.1%. Does this sound like I'm on track?

Yes, the way our professor taught us, all the exit values under constant entropy are marked with subscript s.

Homework Statement Water vapor at 6 MPa, 600C enters a turbine operating at steady state and expands to 10 kPa. The mass flow rate is 2 kg/s, and the power developed is 2626 kW. Stray heat transfer and kinetic and potential energy effects are negligible. Determine (a) the isentropic turbine...

Homework Statement As shown in Fig. P5.39, a system undergoing a power cycle develops a net power output of 1 MW while receiving energy by heat transfer from steam condensing from saturated vapor to saturated liquid at a pressure of 100 kPa. Energy is discharged from the cycle by heat transfer...

Chester, With your hint, I was able to find a final temperature of 1600, and corresponding internal energy values of u1 = 142.56 kJ/kg, and u2 = 1298.30 kJ/kg, according to the tables in the back of my textbook. I calculated the corresponding change in internal energy to be 4.0289 kJ. The...

Homework Statement Air contained in a piston–cylinder assembly, initially at 2 bar, 200 K, and a volume of 1 L, undergoes a process to a final state where the pressure is 8 bar and the volume is 2 L. During the process, the pressure–volume relationship is linear. Assuming the ideal gas model...

Hello Physics Forums! Despite what the username says, I am neither a Giant, a 49er, or a Golden State Warrior...I am a fan of all those teams, but that's beside the point, hehe. I'm currently in the third year of the Mechanical Engineering program at my school, which is where the nitty-gritty...
