Naik, Sameer V. Spring 2011 Lecture 34 Example Solution Given: - Ideal Rankine cycle with given boiler and condenser pressures Find: - T-s diagram - Net power (kW) developed by the cycle - Thermal efficiency (%) of the cycle - Mass flow rate (kg/s) of cooling water in the condenser System: Condenser Boiler Pump Turbine W turbine W pump Q in P 1 = 16 Mpa saturated vapor P 2s = 8 kPa P 3 = 8 kPa saturated liquid T cooling water = T out – T in = 18 C P 4s = 16 MPa Assumptions: - Steady state - Negligible changes in KE and PE in all devices - Negligible pressure drop in boiler and condenser - Adiabatic and reversible turbine and pump - No heat transfer to surroundings for condenser - No mechanical work interaction for boiler and condenser Basic Equation(s):  f gf y yx yy 
