Air is flowing in parallel over the upper surface of a
flat plate with a length of 4 m. The first half of the plate length,
from the leading edge, has a constant surface temperature
of 50°C. The second half of the plate length is subjected to
a uniform heat flux of 86 W/m2. The air has a free stream
velocity and temperature of 2 m/s and 10°C, respectively.
Determine the local convection heat transfer coefficients at
1 m and 3 m from the leading edge. Evaluate the air properties
at a film temperature of 30°C. Is the film temperature
Tf = 30°C applicable at x = 3 m?
