For laminar free convection from a heated vertical
Chapter 6, Problem 6.8(choose chapter or problem)
For laminar free convection from a heated vertical sur-face, the local convection coefficient may be expressedas hx?Cx?1/4, where hxis the coefficient at a distance xfrom the leading edge of the surface and the quantity C,which depends on the fluid properties, is independent ofx. Obtain an expression for the ratio x/hx, where xis theaverage coefficient between the leading edge (x?0) andthe x-location. Sketch the variation of hxand xwithx.
