Superheated water vapor enters a turbine that transfers 1 MW of power to a generator which is coupled by a shaft. The steam expands following a polytropic process that follows the relationship: pv3,8 = cte. Assume that the turbine transfers heat to the medium at a rate corresponding to 0.01% of the shaft power produced. So determine the final state (p2, v₂) Superheated water vapor enters a turbine that transfers 1 MW of power to a generator which is coupled by a shaft.
