Extracted text: 2. 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. (iv) Determine the specific enthalpy values at the four key points of the cycle. (v) Calculate the specific heat provided to the boiler, the specific work extracted from the power station and the mass flow rate of the steam circulating in the cycle (vi) Determine the thermal efficiency of the cycle.
