Question

<p>Fundamentals of Heat and Mass Transfer (6th edition Incropera) (Problem# 11.81 pg 721)<br /><br />Consider the conditions in Example 11.6, but with the continous fin arrangement of fig. 11.17 used in lieu of the circular fins of fig. 11.16. The heat exchanger core is fabricated from Al., and the tubes have an inside diameter of 8.2mm. An inside convection coefficient of 1,500 W/m²K may again be assumed for water flow through the tubes, with combustion gases at 1 ATM and 825K in cross flow over the tubes.&#160; For a gas flow rate of 1.25 kg/s and a frontal area of .20 m² , what is the gas-side overall heat transfer coefficient?&#160; If water at a flow rate of 1 kg/s is to be heated from 290K to 370K, what is the required heat exchanger volume?</p>
