In a process change, it is desired to cool 2 ton./h of aniline to 95°C. For this, there is a double tube heat exchanger available at the plant that has an area of 3.0 m2 on the external surface of the inner tube and is unused (deactivated at the moment). A stream of toluene at a flow rate of 5 ton. / h and 30ºC is available for this and can be used with the exchanger in question operating in opposite currents as a recuperator. What is the outlet temperature of both fluids? Data U=350Kcal/(h m2 °C); Cp, aniline = 0.54Kcal/(Kg°C); Cp , toluene = 0.42 Kcal/(Kg °C). Calculate the exit temperature of aniline and toluene in °C. Both rounded to one decimal place after the decimal point.

Question
In a process change, it is desired to cool 2 ton./h of aniline to 95°C. For this, there is a double tube heat exchanger available at the plant that has an area of 3.0 m2 on the external surface of the inner tube and is unused (deactivated at the moment). A stream of toluene at a flow rate of 5 ton. / h and 30ºC is available for this and can be used with the exchanger in question operating in opposite currents as a recuperator. What is the outlet temperature of both fluids? Data U=350Kcal/(h m2 °C); Cp, aniline = 0.54Kcal/(Kg°C); Cp , toluene = 0.42 Kcal/(Kg °C).
Calculate the exit temperature of aniline and toluene in °C. Both rounded to one decimal place after the decimal point.
