A counter-flow heat exchanger is attached to a stenter for waste heat recovery.
Consider the following data:
Ambient temperature: 30 °C
Temperature of exhaust from stenter: 150 °C
Temperature of exhaust at exit of heat exchanger: 100 °C
Specific heat of exhaust: 0.42 kcal/°C/kg
Specific heat of air: 0.24 kcal/°C/kg.
At steady state, if the mass flow rates of the exhaust gas and the incoming air are the same, assuming heat loss as zero, what is the temperature (°C) of the air at the exit of the heat exchanger (towards the stenter)? (Round off to one decimal place).
