Final answer:
To calculate the rate of heat conduction, determine the thermal resistance of each layer of the wall and use the formula Q = (Th - Tc) / R. To balance the heat transfer, divide the heat transfer rate by the power of each room heater.
Step-by-step explanation:
In order to calculate the rate of heat conduction through the house walls, we first need to determine the thermal resistance of each layer of the wall.
The thermal resistance is calculated by dividing the thickness of each layer by its thermal conductivity.
The total thermal resistance of the wall is the sum of the thermal resistances of each layer.
Once we have the thermal resistance, we can use the formula Q= (Th - Tc) / R to calculate the rate of heat conduction, where Q is the heat transfer rate, Th is the temperature of the inside surface, Tc is the temperature of the outside surface, and R is the thermal resistance.
To balance the heat transfer due to conduction, we need to calculate the number of 1-kW room heaters needed. We can do this by dividing the heat transfer rate by the power of each room heater.
