Answer:
The thermal conductivity of the biomaterial is approximately 1.571 watts per meter-Celsius.
Explanation:
Let suppose that thermal conduction is uniform and one-dimensional, the conduction heat transfer (), measured in watts, in the hollow cylinder is:
Where:
- Thermal conductivity, measured in watts per meter-Celsius.
- Length of the cylinder, measured in meters.
- Inner diameter, measured in meters.
- Outer diameter, measured in meters.
- Temperature at inner surface, measured in Celsius.
- Temperature at outer surface, measured in Celsius.
Now we clear the thermal conductivity in the equation:
If we know that ,
,
,
,
and
, the thermal conductivity of the biomaterial is:
The thermal conductivity of the biomaterial is approximately 1.571 watts per meter-Celsius.
