Determine the convection heat loss from both the top and the bottom of a flat plate at T s = 80 ° C with air in parallel flow at T ∞ = 25 ° C, u ∞ = 3 m/s . The plate is t = 1 mm thick, L = 25 mm long, and of depth w = 50 mm . Neglect the heat loss from the edges of the plate. Compare the convection heat loss from the plate to the convection heat loss from an L c = 50 -mm- long cylinder of the same volume that of the plate. The convective conditions associated with the cylinder are the same as those associated with the plate

Assume the critical Reynolds number for the flow to be considered as laminar over a flat plate is
5 × 105. Determine the distance from the leading edge at which transition will occur for
atmospheric air when u∞ = 1 m/s and T∞ = 27 °C. Use T∞ to find relevant properties in Table
A.4.
