###### Question details

1. Consider flow over a flat plate for which it is desired to determine the average heat transfer coefficient over the short span x1 to x2 , , where (x2 – x1 ) << L. Provide three different expressions that can be used to evaluate in terms of (a) the local coefficient at x = (x1+ x2 )/2, (b) the local coefficients at x1 and x2 , and (c) the average coefficients at x1 and x2 . Considering whether the flow is laminar, turbulent, or mixed, indicate when it is appropriate or inappropriate to used each of the equations.
