A carpenter builds an exterior house wall with a layer of wood 3.0 cm thick on the outside and a layer of Styrofoam insulation 2.2 cm thick on the inside wall surface. The wood has a thermal conductivity of 0.080 W/(m⋅K), and the Styrofoam has a thermal conductivity of 0.010 W/(m⋅K). The interior surface temperature is 16.0 ∘C, and the exterior surface temperature is -11.0 ∘C.
Part A What is the temperature at the plane where the wood meets the Styrofoam?
Part B What is the rate of heat flow per square meter through this wall?

A flat wall is exposed to an environmental temperature of 38
degrees C. The wall is covered with a layer of insulation 2.5 cm
thick whose thermal conductivity is 1.8 W/(m.K), and the
temperature of the wall on the inside of the insulation is 320
degrees C. The wall loses heat to the environment by convection.
Compute the value of the convection heat transfer coefficient that
must be maintained on the outer surface of the insulation to ensure
that the...

A 1.9-cm-thick wood floor covers a 4.0m×5.5m room. The subfloor
on which the flooring sits is at a temperature of 16.1 ∘C, while
the air in the room is at 19.2 ∘C. What is the rate of heat
conduction through the floor? Use 0.200 W/m⋅K for the thermal
conductivity of wood.

A clever student decides to produce and sell windows that
consist of two 5.9-mm thick glass panes ( thermal conductivity of 1
W/m-K) separated by a 0.9-cm thick layer of aerogel, which has a
thermal conductivity of 10-4 W/m-K). Assuming the
temperature inside is 19.5˚ C, and the temperature outside is
-4.7˚C, what is the approximate heat loss in units of Watts through
such a window with area 1 m2?

A
40-mm-thick plain wall of thermal conductivity 0.04 W/m-K and of
temperature 304 K is exposed to both cold fluid and surroundings
both at 298 K. The cold fluid and wall provide that the heat
transfer coefficient is 10.5 W/m2-K and the emissivity of the wall
is 0.83. Given that the area of the wall is 1.5m2 If the total heat
transferred is 140.6987W, find the temperature of the other side of
the plain wall
