Unformatted text preview: Are the results what you would expect? 3. Problem 7.88, Incropera, et al., 6 th Edition (7.94 in 7 th edition), using the Zukauskas correlation for tube bundles in cross flow (Equation 7.64). Suggestion: Set up a spreadsheet with properties evaluated at T i and T s . Guess a value of T o , evaluate the properties at T m by interpolation, and calculate Nu . Now ( ) LM T DL h N q = From an energy balance, ( ) i o p T T C m q = Use the Solver tool to set the difference between the two heattransfer rates equal to zero by changing T o . The specific heat capacity is evaluated at the average temperature, T m . 4. Repeat Problem 3 using a triangular staggered pitch with S T = S D = 60 mm. Which layout has the higher average heat transfer coefficient? Which has the higher pressure drop? Why?...
