Webb15 okt. 2024 · A NASA scientist has cooked up plans for a bonkers new rocket engine that can reach close to the speed of light – without using any fuel. Travelling at such speeds, the theoretical machine... The efficiency of a heat engine relates how much useful work is output for a given amount of heat energy input. From the laws of thermodynamics, after a completed cycle: and therefore where is the net work extracted from the engine in one cycle. (It is negative, in the IUPAC convention, since work is done by the engine.) is the heat energy taken from the high tem…

WebbCertain other types of heat engines can match the Carnot engine in theoretical performance. The Stirling engine is one example of this. Therefore, the Carnot efficiency at a given hot section and cold section temperature is equal to the Stirling efficiency between the same hot and cold sections. Webb22 maj 2024 · An ideal heat engine is an imaginary engine in which energy extracted as heat from the high-temperature reservoir is converted completely to work. But according to the Kelvin-Planck statement, such an engine would violate the second law of thermodynamics, because there must be losses in the conversion process.
