Question
Determine heat loss of the brick wall.

Transcribed Image Text:A brick wall (k =0.9) of thickness 0.18 m separates the
warm air in a room from the cold ambient air On a particular
winter daw the outside air temperature is -5°C and the room
needs to be maintained at 27°C. The heat transfer coefficient
associated with outside air is 20 ().Neglecting the
convective resistance of the air inside the room, the heat loss
