In a parallel flow heat exchanger operating under steady state, hot liquid enters at a temperature T${_h},{_i}{_n}$ and leaves at a temperature T${_h},{_o}{_u}{_t}$. Cold liquid enters at a temperature T${_c},{_i}{_n}$ and leaves at a temperature T${_c},{_o}{_u}{_t}$. Neglect any heat loss from the heat exchanger to the surroundings. If T${_h},{_i}{_n}$ >>T${_c},{_i}{_n}$, then for a given time interval, which ONE of the following statement is true?

  1. Entropy gained by the cold stream is GREATER than entropy lost by the hot stream
  2. Entropy gained by the cold stream is EQUAL than entropy lost by the hot stream
  3. Entropy gained by the cold stream is LESS than entropy lost by the hot stream
  4. Entropy gained by the cold stream is ZERO
