A parallel flow heat exchanger has hot $,$ inlet temperature $=343K$ and cold $,$ inlet temperature $=298K$ streams. The heat transfer area is $0\mathrm{.}605m^2$ and the overall heat transfer coefficient is $800\frac{W}{m^2(K)}.$ The heat capacity of both streams is $4187\frac{J}{kgK}.$

Calculate the outlet temperatures of both streams.

$lon=\frac{1-e^{-\text{N}\text{T}\text{U}(1+C)}}{1+C}$;$C=\frac{C_{\text{m}\text{i}\text{n}}}{C_{\text{m}\text{a}\text{x}}}$
