Please find the highest thermal efficiency possible, while remaining within the boundaries. What is required: -Power produced must be at least 60 Mega Watts -Thermal efficiency must be greater than 36% -Back-work ratio must be smaller than 48% Assume: -air is the working fluid -specific heats vary with temperature (use table A-17) -Compressor inlet is at 1atm and 300k -the combustion process is isobaric and is modeled as a heat exchanger -Turbine exhaust is the same pressure as compressor inlet Compressor specifics: -Max volume flow rate (m^3/h) = 600,000 -Max outlet pressure (atm) = 12 -Isentropic efficiency = 90% Combustion chamber and gas tubine specifics (Note these come as a set) -Max pressure = 16.7 atm -Max temp = 1500 (celcius) -Turbine isentropic efficiency = 92% -Max heat rate = 230MW

Task 03 B) Double-pipe heat exchangersare used in many industries because of their low design and maintenance costs, flexibility, and low installation cost. They are mainly used for sensible heating or cooling of process fluids in applications of small heat transfer Water at the rate of 68 kg/min is heated from 35 0C to 75 0C by an oil having specific heat of 1.9 kg/kJ.0C . The fluids are used in a counter flow double-pipe heat exchanger, and the oil enters in the exchanger at 175 0C and leaves at 140 0C . The overall heat transfer coefficient is 320 W/m2. 0C . Apply heat transfer formulae to heat exchangers and calculate the heat exchanger area.
Project 5: Automobile radiator, condenser, evaporator, air preheater, and cooling tower are common types of direct heat exchangers that also called recuperators. Recuperators may have different types based on the flow arrangement of the hot and cold fluid. Your role in a company that manufactures recuperators heat exchanger is to design a counter-flow recuperator (see Figure.6) that is used in heating, ventilation, and air conditioning (HVAC). Section.1: − Exhaust pipe is 88 ?? diameter. − Exhaust gas enters at 500??. − Water jacket is used and enters at 8??. − The surface heat coefficient of water and gas are ℎ????? = 300 ?/(?2.?) and ℎ??? = 1500 ?/(?2.?) , respectively. − Assume conduction transfer through wall is negligible. − The gas heat specific capacity is ?? is 1130 ?/(??.?). − The water heat specific capacity is ?? is 4190 ?/(??.?). − The flow rate of gas and water are 320 and 1500 ??/h, respectively. − The gas must be cooled to 100??.
