WebCARNOT CYCLES Sadi Carnot was a French physicist who proposed an “ideal” cycle for a heat engine in 1824. Historical note – the idea of an ideal cycle came about because engineers were trying to develop a steam engine (a type of heat engine) where they could reject (waste) a minimal amount of heat. This would produce the WebCarnot Cycle. Area inside of TS curve is Q. H Area inside of PV curve is W. S Efficiency is the ratio of these two. Carnot Cycle. 1) T. c = 374°C T. coal = 1800°C Operation with superheated steam has a lower D. T. 2) Wet steam kills turbine blades. 3) Complex to compress mixed V/L stream. Webb) The contents of the freezer in a home refrigerator are maintained at 253 K(-20 0 C). The kitchen temperature is 293 K (-20 0 C). If heat leaks amount to 125000 W per day, and if electricity costs $0/kWh, estimate the yearly cost of running the refrigerator. Assume a coefficient of performance equal to 60% of the Carnot value. 6 Marks 5 Marks. 8. drukarnia uds
