1.1 Consider the fireclay brick wall of Example 1.1 that is
operating under different thermal conditions. The tem-
perature distribution, at an instant in time, is T(x) = a+
bx where a 1400 K and b = -1000 K/m. Determine
the heat fluxes, q", and heat rates, q, at x = 0 and x = L.
Do steady-state conditions exist?
2.4 To determine the effect of the temperature dependence
of the thermal conductivity on the temperature dis-
tribution in a solid, consider a material for which this
dependence may be represented as
k = k₁ + aT
where k, is a positive constant and a is a coefficient that
may be positive or negative. Sketch the steady-state
temperature distribution associated with heat transfer
in a plane wall for three cases corresponding to a > 0,
a = 0, and a < 0.

- 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.arrow_forward1.12 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.arrow_forwardPLEASE SOLVE STEP BY STEP WITHOUT ARTIFICIAL INTELLIGENCE OR CHATGPT SOLVE BY HAND STEP BY STEParrow_forward
