Heat addition in carnot cycle
Web16 de ene. de 2024 · For the Carnot cycle isothermal expansion the heat source (thermal reservoir) temperature is infinitesimally greater than the gas temperature in order for heat transfer to be possible. Then the ideal gas does an infinitesimal of work equal to the infinitesimal amount of heat transferred in, thereby keeping the gas temperature constant. Web10 de abr. de 2024 · It will flow in the other direction: from the engine to the reservoir. So you will not get any work output from such a Carnot engine (but you might provide work input and use it as a heat pump). When we use the Carnot cycle to provide work output, we want the heat flow at both reservoirs to be reversible (in the thermodynamic sense of the …
