### Heat Transfer Day 2

### Heat Transfer Day 2

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.

### Heat Transfer Day 3

### Heat Transfer Day 3

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).

### Heat Transfer Day 4

### Heat Transfer Day 4

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.

### Heat Transfer Day 5

### Heat Transfer Day 5

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...
