Heat transfer
A wooden wall in a house is 2dm thick and =0.14W/(m*K). The generating heat was enough to reach a temperature of 15oC inside the house, while the outside temperature is -20oC.
The heat transfer coefficient on the inside and outside the wall is 10 W/m2K.
How much thicker must the wall be to reach a temperature of 21oC inside the house?
Hint: Heat loss through other surfaces in the house is the same as for the wooden wall
