Consider a small turbine running on a 1000 kPa 400 ° C superheated steam feed. The steam leaving the turbine is saturated at 10 kPa and with a titer of 0.95. Due to the need to heat another stage of the industrial process, the turbine is intervened to extract steam at an intermediate point (between the steam inlet and outlet), which is at 100 kPa and an enthalpy of 2,716.6 kJ / kg. The quantity of mass of steam extracted corresponds to 10% of the circulating steam and leaves at negligible speed.
Data: 1 bar = 100 kPa = 0.1 MPa; 1 kW = 1 kJ / s
Is this process isentropic?
