Question. For flow over a flat plate, the relevant Reynolds number for local heat transfer coefficients is Rex (the Reynolds number with the distance from the leading edge of the plate being the length scale). Based on the correlation for local Nusselt number for laminar flow over a flat plate Nux = 0.332Re 2/3p.1/3 (Eq. (7.23) in the 6th Ed.) how does the local heat transfer coefficient (h) vary along the length of the plate? The heat transfer coefficient increases as x increases. The heat transfer coefficient decreases as x increases. The heat transfer coefficient does not depend on x. The dependence can not be observed from this equation.

Question.
For flow over a flat plate, the relevant Reynolds number for local heat transfer coefficients is
Rex (the Reynolds number with the distance from the leading edge of the plate being the length
scale). Based on the correlation for local Nusselt number for laminar flow over a flat plate
Nux = 0.332Re 2/3pr1/3 (Eq. (7.23) in the 6th Ed.)
how does the local heat transfer coefficient (h) vary along the length of the plate?
The heat transfer coefficient increases as x increases.
The heat transfer coefficient decreases as x increases.
The heat transfer coefficient does not depend on x.
The dependence can not be observed from this equation.
