Question

A 15 MW steam-driven turbine operates in the steady-state using 30

kg/s of steam. The inlet condition for the steam is p = 3000 kPa and

450 oC. The outlet condition is 500 kPa, saturated vapor. The

entering velocity of the steam is 250 m/s and the exiting velocity is

40 m/s. What is the transfer in kW for the turbine as the system?

What fraction is the heat transfer of the power generated?
