Answer:
The rate of heat loss through the wall is 1700 watts.
Explanation:
The complete statement of the problem is:
<em>The wall of an industrial furnace is constructed from 0.15-m-thick, fireclay brick having a thermal conductivity of 1.7 W/m·K. Measurements made during steady state operation reveal temperatures of 1400 and 1150 K at the inner and outer sur- faces, respectively. What is the rate of heat loss through a wall that is 0.5 m by 1.2 m on a side?</em>
Given that wall of the industrial furnace is under steady conditions of heat transfer and whose configuration is a flat element, we use the equation of conductive heat transfer rate (), measured in watts:
Where:
- Thermal conductivity, measured in watts per meter-Kelvin.
- Width of the wall, measured in meters.
- Height of the wall, measured in meters.
- Thickness of the wall, measured in meters.
- Inner surface temperature, measured in Kelvin.
- Outer surface temperature, measured in Kelvin.
If we know that ,
,
,
,
and
, the steady state heat transfer is:
The rate of heat loss through the wall is 1700 watts.
