An external wall of a building has a U value of 0.50 W/m^2K. The indoor temperature is 21 degrees C and the outdoor temperature is -2.0 degrees C The steady-state heat loss is calculated to be 11.5W/m^2 The wall contains a layer of insulation 40 mm thick with a conductivity of 0.035 W/mK. What would the insulation thickness need to be in order to reduce the steady state heat loss by 50%? answer = 0.11m ​​​​​​​please show all working

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
