A medium size power station is used to produce 30 MW net power for a refinery. The station uses steam as the operating fluid and operates according to the Carnot cycle between the pressure limits of 0.4 bar and 35 bar. Steam enters the boiler as a saturated liquid and leaves it as a dry saturated vapour.














(viii) Calculate the thermal efficiency of the power station if the isentropic efficiency of the steam turbine is 94%.
