Video Synthesis
  • - Problem: Steam enters a 65% efficient turbine at a thousand degrees and 1200 psi and exits at 250 psi.
  • - Key step: And then since we know the efficiency is only 65% the actual change in enthalpy will only be 65% of what it could be.
  • - Watch out: Now it's not obvious whether this is still superheated steam or if this steam has become saturated if there's been some condensing in the turbine.
  • - Result: It's going to be h1 minus delta h actual which is 1500 minus 132 equals 1368.
  • - ✅ Answer: D
