Question: For laminar flow over a flat plate, the local heat transfer coefficient h. is known to vary as x1/2, where x is the distance from

For laminar flow over a flat plate, the local heat transfer coefficient h. is known to vary as x–1/2, where x is the distance from the leading edge (x = 0) of the plate. What is the ratio of the average coefficient between the leading edge and some location x on the plate to the local coefficient at x?
