4. Calculate the power generated using a Geothermal energy which enters at 73 C and leaves at 54.8 and use R 245 fa as the organic fluid. The cycle is shown below. The stream details in the cycle refers to flow/ P/T and Enthalpy. Calculate the efficiency of the ORC cycle and compare the same to that of Carnot efficiency. Flow in kg/s Enthalpy in kj/kg Pressure in bar Temp in C 42.68 239 2 Geothermal 114 229.45 109470 Evaporator SOURCE 15430566 Power Turbine 4425 Generator 42804335 2001 104 Condenser 4229900 Pamp Quality check point Coaling Water 302113436 1.24 32012
