In a parallel flow heat exchanger operating under steady state, hot liquid enters at a temperature Th,in and leaves at a temperature Th,out. Cold liquid enters at a temperature Tc,in and leaves at a temperature Tc,out. Neglect any heat loss from the heat exchanger to the surrounding. If Th,in>>Tc,in then for a given time interval, which ONE of the following statements is true?
A
Entropy gained by the cold stream is GREATER than entropy lost by the hot stream
B
Entropy gained by the cold stream is EQUAL to the entropy lost by the hot stream
C
Entropy gained by the cold stream is LESS than the entropy lost by the hot stream
D
Entropy gained by the cold stream is ZERO

Correct : a
