Analysis of a Vapor Power Plant

Analysis of a Vapor Power Plant 8/20/96 ME1361 Thermo II 3.0         Abstract The objective of this cite is to construct a computer model of a unbendable vapor power plant. This model go away be aim to calculate the state properties at all points within the cycle. overwhelm is an digest of the ideal extraction pressures based on the c atomic number 18ful value of net work, energy input, thermal efficiency, moisture content, and effectiveness. 4.0          form 4.1         Introduction System to be Analyzed Steam enters the firstly turbine set at 120 bar, 520 °C and expands in tierce stages to the condenser pressure of .06 bar. Between the first and befriend stage, both(prenominal) steam is diverted to a closed feedwater fume at P1, with saturated liquid condensate being manage in the lead into the boiler feedwater line. The Terminal Temperature Difference of the feedwater heater is 5°C. The backup of the steam is reheate d to 500°C, and then enters the second stage of expansion. leave of the steam is extracted between the second and third stages at P2 and federal official into an open feedwater heater operating at that pressure. gross(a) liquid at P2 leaves the open feedwater heater. The efficiencies of all pumps are 80%, and the efficiencies of all turbines are 85%. Throughout this report the states will be reference as depicted in a higher localise with the numbers 1-13. The analysis of the system will involve the substance abuse of the Energy put difference to isolate the specific enthalpies and associated values of temperature, pressure, specific volume, and steam quality. The Entropy balance equation will be use to calculate the specific entropy at all the above noted states. Energy Rate Balance (assume KE&PE=0) dEcv/dt = Qcv-Wcv+Smi(hi) - Sme(he) Entropy Rate Balance dScv/dt = SQj/Tj + Smi(si) - Sme(se) + scv For simplicity, it is fake in all calculations that...
