(20 points) A finned-tube, cross-flow heat exchanger has a gas-side area of 10 m2 and an overall heat transfer coefficient of Uh = 154 W/m2K. Hot gas (cp,h = 1050 J/kg∙K) enters the gas side at a mass flow rate of 1.5 kg/s and an inlet temperature of Th,i = 325℃. Cold water (cp,c = 4200 J/kg∙K) enters the liquid side at a mass flow rate of 0.5 kg/s and an inlet temperature of Tc,i = 35℃. Determine the heat transfer rate. Use the effectiveness-NTU data shown below for your calculation.
