Q2. Consider an ideal Rankine cycle where the boiler operates at 12.5 MPa and thecondenser operates at 40 kPa. The steam is superheated after the boiler to 600 oC. Theturbine produces 100 MW of shaft work. Determine:a) The mass flow rate of water through the turbine (in kg/s).b) The work required for the pump.Q3. For the process in Q2. Determine:a) The heat input into the boiler (in MW).b) The heat out for the condenser (in MW)c) The thermal efficiency of the cycle (in %).

Reheating increases the enthalpy and entropy of the steam entering the turbine which allows more power to be extracted from the turbine for a given condenser pressure. Wouldn't simply superheating the inlet to a single turbine have the same effect?Question 3Select one:a.No superheating will require the addition of more heatb.No super heating will increase the entropy but it will not increase the enthalpyc.Yes both will have the same effects but superheating would reduce the quality of steam in the turbined.Yes but superheating would involve a higher turbine inlet temperaturee.Yes but superheating will not allow the use of inter-cooling

For a simple ideal Rankine cycle, which uses water as the working fluid, the work produced by the turbine is 962.37 kJ/kg and heat supplied in the boiler is 2,568.32 kJ/kg . The condenser operates at 8 kPa and its boiler operates at 8,614 kPa. Use v1 = 0.001008 m3/kg  in your calculations.Note: v-specific volumeAssumptions:Steady operating conditionKinetic and potential energy changes are negligible.Determine the thermal efficiency in % of this Rankine cycle when steam enters the turbine without any super-heating.
