Heat loss through a composite wall of three materials.xls

Rating:
3

Description

KNOWN: Thicknesses of three materials which form a composite wall and thermal conductivities of the two materials. Inner and outer surface temperatures of the composite: also, temperature and convection coefficient associated with adjoining gas.
FIND: Value of unknown thermal conductivity, kB.
ASSUMPTIONS: 1) Steady-state conditions
2) One-dimensional conduction
3) Constant properties
4) Negligible contact resistance
5) Negligible radiation effects
ANALYSIS: Analogy with thermal circuit.
