Question Ref. No: $405$

An adiabatic turbine uses steam as the medium and it operates steadily at pressure of $6$ Mpa, temperature of $600$ oC and velocity inlet of $47$ m$/$s$.$ The steam expands in the turbine and exits at pressure of $10$ kPa and velocity of $81$ m$/$s$.$ During the process, the power produced by the turbine is $6$ MW and the isentropic efficiency is $50\%.$
