In a counter flow heat exchanger, the working parameters for hot fluid are as follows: heat capacity = 2 kJ/kg K, mass flow inlet temperature 150oC , outlet temperature 100oC. For the cold fluid, the parameters are: heat capacity = 4 kJ/kg K, - mass flow rate 10 kg/s, and inlet temperature is = 20oC. The outlet temperature of the cold fluid in oC is
  • a)
    7.5
  • b)
    32.5
  • c)
    45.5
  • d)
    70.0
Correct answer is option 'B'. Can you explain this answer?

From steady state flow energy equation
mhcph(Thi - The) = mccpc(Tce - Tci)
∴ 5 x 2000(150 -100) = 10 x 4000(Tce - 20)
Tce = 32.5oC
