LinBoiler i4PumpTurbineWW₁LoutCooling waterCondenserA steam turbine operating on the Ideal Rankine cyclereceives steam with a flow rate of 5400 kg/h, at a pressureof 15 bar and a temperature of 450 °C. In the condenser,seawater circulates at 32 °C (condenser pressure is 10kPa). Given that the lower heating value of the fuel used inthe boiler is 40700 kJ/kg, find the thermal efficiency of thesystem for the three options listed below.a) In case of 5-10-15% steam loss between the boiler and the turbine,b) Between turbine and condenser 5-10-15% steam loss to be in case,c) 10% steam loss between boiler-turbine and turbine-condenser calculate in case.

A medium size power station is used to produce 30 MW net power for arefinery. The station uses steam as the operating fluid and operatesaccording to the Carnot cycle between the pressure limits of 0.4 bar and35 bar. Steam enters the boiler as a saturated liquid and leaves it as adry saturated vapour. (i) Calculate the thermal efficiency of the power station if theisentropic efficiency of the steam turbine is 94%. (ii) State main disadvantages of using the Carnot cycle as the basis fora power station. (iii) State the name of the cycle that is used in practice in powerstations, along with three key benefits over the Carnot cycle.
It is proposed to design and develop a Rankine cycle Steam Power Plant in which steam at 80 barand 500 oCis supplied to the turbine which exhausts at a pressure of 0.11 bar into a condenser. Condensate from the condenser is returned to Steam Generator (Boiler) by a Feedwater Pump. The processes in the turbine and pump can be assumed to be reversible adiabatic. In addition, pressure and temperature drops can be neglected throughout the cycle. Sketch the T-s diagram for this cycle and calculate the following performance parameters:i) Cycle Thermal Efficiency ii) Work Ratioiii) Specific Steam Consumptioniv) Condenser Heat Loadv) Mass flow rate of steam to generate a net power output of 40 Megawatts (MW).vi) Mass flow rate of cooling water required for the condenser if the cooling water inlettemperature is 26 oC and its outlet temperature is limited to 40 oC.

Consider a simple ideal Rankine cycle with fixed boiler and condenser pressures.. Whathappens if the steam is superheated to a higher temperature?
Steam at 10 MPaa, 550 degrees celsius enters an ideal engine that has one stage of regenerative cycle; condenser pressure is 10kPaa and extraction of steam is at 1 MPa.
Complete and legible solution please; The condensing pressure for a Rankine engine is 1 bar. Calculate the work net in KW and thermal efficiency of the cycle when the steam at the beginning of expansion is at 50 bar and (a) saturated, (b) 350 OC, and (c) 640 OC. Note: 1 bar is equal to 100 Kpa
The net work output and the thermal efficiency for the Carnot and the simple ideal Rankinecycles with steam as the working fluid are to be calculated and compared. Steam enters theturbine in both cases at 10 MPa as a saturated vapor, and the condenser pressure is 20 kPa.In the Rankine cycle, the condenser exit state is saturated liquid and in the Carnot cycle, theboiler inlet state is saturated liquid. Draw the T-s diagrams for both cycles.
