2013-3-6 The Rankine Cycle interconnect comp onents of s Fig.8.1(a) undergoes a thermodynamic cycle known as the Rankine cycle There are four principal control volumes involving these components: Turbine Condenser >Pump Boiler All energy transfers by work and heat are taken as positive in ns of the a s on the schematic and energy written accordingly. The Rankine Cycle The processes of the Rankine cycle are Process1-2:vapor expands through the turbine developing work Process 2-3:vapor condenses to liquid through heat transfer to cooling water Process 3-4:liquid is pumped into the boiler requiring work input Process 4-1:liquid is heated to saturation and evaporated in the boiler through heat transfer from the energy source 10 2013-3-6 10 The Rankine Cycle ►Each unit of mass of water circulating through the interconnected components of Subsystem B of Fig. 8.1(a) undergoes a thermodynamic cycle known as the Rankine cycle. All energy transfers by work and heat are taken as positive in the directions of the arrows on the schematic and energy balances are written accordingly. ►There are four principal control volumes involving these components: ►Turbine ►Condenser ►Pump ►Boiler The Rankine Cycle Process1-2: vapor expands through the turbine developing work Process 2-3: vapor condenses to liquid through heat transfer to cooling water Process 3-4: liquid is pumped into the boiler requiring work input Process 4-1: liquid is heated to saturation and evaporated in the boiler through heat transfer from the energy source ►The processes of the Rankine cycle are
