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...

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:...

Uniform area, heat transfer problem A stove's walls are made up
of a flat inner insulating board 0.01m thick (thermal conductivity:
0.2 W m-1K-1) and a flat outer steel sheet
0.01m thick (thermal conductivity: 26 W
m-1K-1). A mineral-wool (thermal
conductivity: 0.065 W m-1K-1) is placed
between these sheets. The inside temperature of the wall is 773K,
how thick does the insulation have to be to maintain the outside
wall temperature at 323K ? Assume that the ambient air temperature...

A 1 m outer diameter spherical tank made of AISI 304 steel with
10 cm wall
thickness contains solid iced water at 0°C. Air at 25°C flows
outside the tank with a
velocity of 1 m/s. Determine the rate of heat transfer to the tank
and the mass rate (
m_dot) at which ice melts. Ignore convection effects of the melting
ice.
The latent heat of fusion of water at 0°C is 333.7 kJ/kg.

An insulated copper wire with a length of 1.2 m carries 20 A of
current. The copper is 1 mm in diameter and the insulation (k=0.13
W/m. ºC) has a thickness of 0.8 cm. The wire has electrical
resistance of 0.0321 Ω. Air at 25 ºC blows in crossflow over the
wire to produce an external convective heat transfer coefficient of
219 W/m2. K. Assuming the copper is isothermal, find the copper
temperature. Take the electrical resistivity of copper to...

1-The temperature value inside a reactor in the treatment plant
is 30 0C during operation. The outdoor temperature in the winter
period is 5oC. The wall thickness of the reactor is 0.10 m and its
area is 20 m2. Air and reactor wall heat transfer coefficients and
conductivity are given below.
reactor = 20W / m2.K, creator = 0.8 W / m.K; outdoor environment =
10 W / m2.K
a. Under these conditions, calculate the heat loss value from the...

Temperatures of gases inside the combustion chamber of a
four‑stroke automobile engine can reach up to 1000 ∘C. To remove
this enormous amount of heat, the engine utilizes a closed
liquid‑cooled system that relies on conduction to transfer heat
from the engine block into the liquid and then into the atmosphere
by flowing coolant around the outside surface of each cylinder.
Suppose that, in a particular 6‑cylinder engine, each cylinder
has a diameter of 8.75 cm, a height of 11.0...
