#### Free Convection: ConcepTest and Example Problem

##### Example Problem 1

A flat plate is oriented vertically in quiescent (still) air. The surface of the plate has a temperature of \(T_s\) = 90°C. The air has a temperature of \(T_∞\) = 25°C.

- Show whether the flow over the plate due to free convection is laminar or turbulent.
- Calculate the average heat transfer coefficient over the surface of the plate, \(\bar{h}\), in units of W/m
^{2}-K. - Calculate the total rate of heat transfer from the right surface of the plate, in units of Watts.
