Experimental results indicate that local heat transfer coefficient h g for flow over a flat plate with an extremely rough surface is approximated by relation
h x = a x -0.12
Where a is a constant coefficient and x is distance from leading edge of plate. What is relation between this local heat transfer coefficient and average heat transfer coefficient for a plate of length x?
