For laminar free convection from a heated vertical surface, the local convection coefficient may be expressed as hy = Cxx-1/4, where h, is the coefficient at a distance x from the leading %3D edge of the surface and the quantity C, which depends on the fluid properties, is independent of x. Obtain an expression for the ratio hy/hx, where x is the average coefficient between the leading edge (x = 0) and the x-location. Sketch the variation of hy and hy with x. %3D

Question
For laminar free convection from a heated vertical surface, the local convection coefficient
may be expressed as hy
Cx-1/4, where h, is the coefficient at a distance x from the leading
edge of the surface and the quantity C, which depends on the fluid properties, is independent
of x. Obtain an expression for the ratio hx/hx, where x is the average coefficient between the
leading edge (x = 0) and the x-location. Sketch the variation of h, and hy with x.
