Heat Transfer and Thermal Conduction Question?
You wish to determine the thermal conductivity of some insulating material that comes in sheets 1.0cm thick. To do this you construct a cubic box whose exterior lengths are 25cm, and place a thermal meter and a 100 W heater inside the box. After thermal equilibrium has been attained, the temperature inside the box is 80-degrees-C when the external temperature is 20-degrees-C. Determine the thermal conductivity of this insulating material.
k = (Q/t)*L/ (A*dT)
Q/t is power = 100 W
L is thickness of 0.01m (1cm)
A is area normal to heat flow = .25m^2 * 6 sides = 0.375 m^2
dT is the temperature difference = 80-20 = 60K (K is same size as C)
Plug in and get k= 0.044 W/(M K)
