QUESTION 3
Consider propane at 558 K and 6 bar fed to an insulated continuous turbine. The pressure is reversibly decreased
by a factor of 4.5. The actual outlet turbine temperature is 499 K . Compute the turbine efficiency while treating
propane as an ideal gas. Express your answer as a fraction not a percentage.
QUESTION 4
Steam initially at 20 MPa and 494 C is expanded adiabatically to 0.5 MPa and saturated vapor. Compute
the turbine efficiency.
