Question

An inverter came to have developed a best engine that the host trom a source : 600 °C und rechts waste heat to a nik maintained at 40 °C. The inventor clima for every 1 kW of energy the hou engine cotto e can produce 0.55 kW of power. O A. The inventors amis OB.invertors is not po OG. There were the ceny Do's cames secondowodnios

Answer 1

Sol Given data :- temperature of source CTH) = 800°C = 800-273 = 1073 K 40°C - 407273 temperature of sink CTL] - 313 k heat engine receiveç Cen) = 1kW Engine Reject Cunett 0.55 kW we know that, thermal efficiency carnot Efficiency (carnot) 1013 k) TL TH I kn +0.55 kn (HE .1-313 313k 1073 .; Y carnot = 70.82997; actual thermal efficiency of the heat Engine Wnet 0.55 Nth CH 1 - 2th 554/ we know that carnot cycle efficiency should be more than efficiency of any heat engine, and the efficiency of given heat Engine iş Less than the caynot cycle Engine Efficiency. So, the inventor claim is valid : The inventors claim is pofsible option-a" is correct answer CG
