Two streams of fluids of unit constant specific heat and unit mass flow rate exchange thermal energy in an adiabatic heat exchanger. The inlet temperature of hot and cold fluid streams is 300 0C and 30 0C respectively. The effectiveness of the heat exchanger if the outlet temperature of both the fluid are equal is
  • a)
    0.5
  • b)
    0.6
  • c)
    0.7
  • d)
    0.8
Correct answer is option 'A'. Can you explain this answer?

Two streams of fluids of unit constant specific heat and unit mass flo...
For zero entropy condition, outer temperature of both the fluid must be same,
Hence, mhCh (300-t) = mhCh (t-30)
t = 105° C
And this condition is possible only in case of counter flow heat exchanger.
