1.21 A one-dimensional plane wall is exposed to convective
and radiative conditions at x = 0. The ambient and sur-
rounding temperatures are T = 20°C and Tur = 40°C,
respectively. The convection heat transfer coefficient is
h=20 W/m² K, and the absorptivity of the exposed sur-
face is α=0.78. Determine the convective and radiative
heat fluxes to the wall at x = 0 if the wall surface tem-
perature is T, = 24°C. Assume the exposed wall surface
is gray, and the surroundings are large.
1.12 You've experienced convection cooling if you've ever
extended your hand out the window of a moving vehi-
cle or into a flowing water stream. With the surface of
your hand at a temperature of 30°C, determine the con-
vection heat flux for (a) a vehicle speed of 40 km/h in
air at -8°C with a convection coefficient of 40 W/m² K
and (b) a velocity of 0.2 m/s in a water stream at 10°C
with a convection coefficient of 900 W/m²K. Which
condition would feel colder? Contrast these results with
a heat flux of approximately 30 W/m² under normal
room conditions.
