The heat reservoir of an ideal carnot

WebA Carnot engine has the maximum possible efficiency of converting heat into work between two reservoirs, but this does not necessarily mean it is 100% 100 % efficient. As the difference in temperatures of the hot and cold reservoir increases, the efficiency of a Carnot engine increases. Example A Carnot Heat Pump Webheat to the cold reservoir as it absorbed when absorbing heat from the hot reservoir. That is Q h T hw = Q c T cw (4) 1. CARNOT ENGINE - A REALISTIC VERSION 2 so Q c =Q h T cw T hw (5) Combining this with 3 gives 1 T h T hw = T cw T ... The ’ideal’ Carnot efficiency for these temperatures is e=1 T c T h =0:659 (22)

WebCorrect option is A) The carnot efficiency is given as η=1− T 1T 2. Here T 1 is the temperature of the hot reservoir and T 2 is the temperature of the coldreservoir. This value of η will be 100% for T 2=0. As all the temperatures are in Kelvin the correct answer is 0K. WebA heat reservoir (Figure 5.3) is a constant temperature heat source or sink. Because the temperature is uniform, there is no heat transfer across a finite temperature difference and the heat exchange is reversible. From the definition of entropy ( ), where is the heat into the reservoir (defined here as positive if heat flows into the reservoir.)
