Consider laminar, parallel flow past an isothermal flat plate of length L, providing an average heat transfer coefficient of hL. If the plate is divided into N smaller plates, each of length L L N = /N, determine an expression for the ratio of the heat transfer coefficient averaged over the N plates to the heat transfer coefficient averaged over the single plate, h h/ L N, , L 1.
