A 0.4 m high, vertical plate being heated electrically with ˙q = 15W/m²
has atmospheric air at a pressure of 0.1 MPa and a temperature of 10 ◦C flowing over it. Calculate the plate temperature over its height.

As the mean boundary layer temperature is unknown, calculate approximately with the material properties of air at 10 ◦C. These are: thermal conductivity λ = 0.02494W/Km, kinematic viscosity ν = 14.42 · 10⁻⁶
m²/s, Prandtl number P r = 0.716, thermal expansion coefficient β∞ = 1/T∞ = 3.532 · 10⁻³
K⁻¹.
