As you read about the three types of heat transfer, pay attention to: What the heat is moving through (solids, liquids and gases, or empty space) How the heat is being transferred (touch, currents, or waves) Conduction 2.3-1 Modes of Heat Transfer Conduction For one dimensional heat transfer by conduction in the x-direction only, the heat transfer rate is given by Q x = - kA dx dT (2.3-4) In this expression, k is a property called the thermal conductivity and A is the area normal to x-direction. In terms of the heat flux q x, we have q x = - k dx dT (2.3-5) Repeat until all the mixture had gone. 7. Place 6-8 falafels in at a time, or however many you can fit it whilst allowing space around them. 8. Flatten them down with the back of a spatula and cook on each side for 3-4 minutes until golden brown. 9. Keep cooked falafels in an oven on low heat whilst the others cook. 10.
