This contains 4 in-class problems on convection and radiation. The first law of thermo shows up again in these which foreshadows its use in later topics. The value of these notes is in the problems; the in-class notes give you the ideas and equations while the problems test how well you understand them.

There are two in-class problems; 1. Given a pond and its rate of heat generation per unit mass, the rate of heat generation for the whole pond is found (in variable form). 2. For a cylindrical container holding radioactive waste, heat is generated at a given rate per unit mass (indicated by e). Expressions for the heat generation rate of the whole container and the temperature at its outer surface are found. The in-class notes review the equations for convection and radiation. Also, a couple sou...

Includes two class problems; first shows the heat generation in an electrical wire and second shows the heat lost from a person to a room due to convection and radiation. The first law of thermo is applied to both problems and will continue to be a valuable approach. The class notes touch more on convection and radiation with their equations and the definitions of the variables in them.

Starts off simple with definitions and equations. The first day of notes is brief and will be the simplest set. The ideas build at a pace that is slow enough to grasp but fast enough not to lose interest. These notes include; a comparison between heat transfer and thermodynamics, first law of thermo, heat flux equation and conduction equation.

These lecture notes include two class problems on conduction. The first problem shows one way to find the heat flux of an object with a given temperature distribution. The second problem shows how doubling a window's thickness can impact its rate of heat loss. The class notes give the heat conduction (Fourier's) equation in one dimension and the definition of the gradient operator (upside-down delta).

Shows the first law of thermodynamics, total energy generation rate for a volume, heat flux and the three ways in which heat is transferred. First law (a.k.a. energy balance) is expressed two ways; first, as a change from an initial time to a final time and second, on a per unit time basis (derivative form). Mentions the three ways heat is naturally transferred between materials.

Brief and simple introduction to Heat transfer. Includes the following: a few definitions, comparison between Thermodynamics and Heat Transfer, 1st law of Thermo, properties that depend on temperature and conversion factors for temperature units.
