From steam table, we can see that at 6Mpa, the saturated steam temperature is 275.68 C. But the condition given is that the temperature of steam at entry is 500 C. This means that the steam must be in super-heated phase.
So the phase of steam entering is superheated.

Please show steps. Steam at 0.3 kg/s enters an adiabatic turbine at 2 MPa and 500°C. It exits at 100 kPa. If the isentropic efficiency is 95%, how much power is produced, in units of kW? Correct Answer is 514.1 m/s Thank you.
In a reheat-cycle power plant, steam enters the high-pressure turbine at 5 MPa, 450°C, and expands to 0.5 MPa, after which it is reheated to 450°C. The steam is then expanded through the low-pressure turbine to 7.5 kPa. Liquid water (Vi 0.001 m/kg) leaves the condensor at 30°C, is pumped to 5 MPa, and returned to the steam generator. Each turbine is adiabatic, with an isentropic efficiency of 81.6 % and the pump efficiency is 848 %. If the total...
