For laminar flow over a flat plate, the local heat transfer coefficient $h_{x}$ is known to vary as $x^{- \frac{1}{2}}$ , 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?
