If the turbine is reversible, how much work is produced per kg of steam?

If the turbine is reversible, how much work is produced per kg of steam?.

Steam is fed to an adiabatic turbine at 4 MPa and 500°C. It exits at 0.1 MPa.

(a) If the turbine is reversible, how much work is produced per kg of steam?

(b) If the turbine is 80% efficient, how much work is produced per kg of steam? .

Methane is compressed in a steady-state adiabatic compressor (87% efficient) to 0.4 MPa. What is the required work per mole of methane in kJ? If the flow is to be 17.5 kmol/h, how much work must be furnished by the compressor (in kW)? What is the rate of entropy generation (in kJ/K/h)? (a) the inlet is at 0.1013 MPa and 240F; (b) the inlet is 0.1013 MPa and 200 K.
