Another one BRA-T — let's solve it.

2.3. Calculate the heat transfer area needed for this heat exchanger, based on an overall heat transfer coefficient of $500 W/m^2\text{K}$ .

Step 1: Calculate the Log Mean Temperature Difference ( $\Delta T_{lm}$ ) for counter-current flow. The temperatures are:

Hot oil inlet ( $T_{h,in}$ ): $200 \text{ °C}$
Hot oil outlet ( $T_{h,out}$ ): $40 \text{ °C}$
Cooling water inlet ( $T_{c,in}$ ): $30 \text{ °
