# SS-V: 3010 Insulated Wall

Test No. VT02 Find temperatures at firebrick and insulating brick surfaces in an insulated wall.

## Definition

A wall consists of two layers: a 9 inch firebrick layer and a 5 inch insulating brick layer. The temperature at firebrick surface is 3000 F and the temperature at the insulating brick surface is 80 F.

**Properties****Value**- Firebrick Thermal Conductivity
- 0.8 BTU/(hr-ft-F)
- Firebrick Convection Coefficient
- 12 BTU/(hr-ft
^{2}-F) - Insulating Brick Thermal Conductivity
- 0.1 BTU/(hr-ft-F)
- Insulating Brick Convection Coefficient
- 2 BTU/(hr-ft
^{2}-F)
