Consider a Carnot’s cycle operating between T1 = 500K and T2=300K producing 1 k J of mechanical work per cycle. Find the heat transferred to the engine by the reservoirs.

Answer :

Efficiency of any system, reversible cycle =



Now, Carnot theorem states that the efficiency of Carnot heat engine depends only on temperature of the source (T1) and temperature of the sink (T2) and is given by



According to question,


Temperature of source, T1=500K


Temperature of source, T2=300K





We can see from the figure that |W|=q2-q1




Now, since



=


=
