Calculations:

Calculate the heat transfer rate $($q$)$ from the water side

$)=(m_{\text{w}\text{a}\text{t}\text{e}\text{r}}^{}{c}_{p,\text{w}\text{a}\text{t}\text{e}\text{r}}(T{)}_{\text{w}\text{a}\text{t}\text{e}\text{r}}$

$($The specific heat value $(c_p)$ of water should be taken at the average of water inlet and outlet temperatures$)$

Calculate the $log$ mean temperature difference $(T{)}_{lm}$

Calculate the overall heat transfer coefficient $(U)$ using

A

$($heat transfer surface area$)=2\mathrm{.}065(m^2)$

$)=(UA(T{)}_{lm}$
