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?
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.

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...
