The Carrot engines A and B are operated in series.  The first one, A receives heat at T1(=600 K) and rejects to a reservoir at temperature T2.  The second engine B receives heat rejected by the first engine and, in turn, rejects to a heat reservoir at T­3(=400K).  Calculate the temperature T2 if the work outputs of the two engines are equal:

a.

400k

b.

600K

c.

500K

d.

300K

Answer Key / Explanation : (c) -

 w1=w2

 u1= u2

T3 –T2 = T2-T1

2T2=T1+T3

T2=500K
