Question

a wall is made with three layers of material. The tempurature on one side of the wall is 30 degrees celcius and on the other side is -15 degrees celcius. Starting at the warm side, the first material has a thickness L1 and the thermal conductivity k1, the second material has thickness L2= 0.7L1 and thermal conductivity k2=0.9k1, and tge third material (one the cold side of the wall) has L3= 0.35L1 and thermal conductivity k3=0.8k1. What is the temperature difference across layer 2?

Answer #1

In a warehouse, a cold room that is maintained at
10oC has a wall made of two layers of
materials. The inner layer has a thickness of 2 cm and a thermal
conductivity of 0.1 W/mK. The outer layer, which is 4 cm thick, has
a thermal conductivity of 0.04 W/mK. The temperature of the outside
ambient is 30oC . The convective heat transfer
coefficients on the outside and the inside of the wall are 40
W/m2K and 20 W/m2K...

It is a question about the thermal heat transfer problem.
A wall consists of 2 layers in parallel: A=3m^2 and B=7m^2. The
indoor air temperature and outdoor air temperature are 20C and 10C,
respectively. The rate of heat flow through the whole wall is not
to exceed 50W by adding a thermal insulation on the wall ( on both
A and B), What is the required thickness of the thermal insulation
layer? The thermal conductivity of the thermal insulation layer...

The initial temperature distribution
across a wall with a thickness of 60 cm is described with the
following function:
T(x) = -250x+100x2+
20x3/ 2x
where T is temperature in
degrees Celsius and x is the coordinate in meters.
The wall has a thermal conductivity of
2.5 W cm-1 K-1.

The wall of an industrial furnace is constructed from a fireclay
brick layer which is covered with another layer of ordinary brick.
The outer surface wall temperature has a steady-state temperature
of 110 °C when the ambient air has a temperature of 20°C. Heat is
lost from the outer surface wall via convection and radiation. The
internal furnace wall has a surface temperature of 500 DegreeC.
Convection heat transfer coefficient between outer wall and air:
5 W/m2K
Stefan-Boltzmann constant σ:...

The
wall of an industrial furnace is constructed from unknown material
