1. Is Your Refrigerator Running? By Michael Root Plus Excel Linear Interpolating Spreadsheet This is a two part project whose parts are unrelated to each other

2. The walls of the refrigerator are made of Plexiglas and sheet metal (with a thin layer of finishing not taken into account)

3. Objective: Find rate of heat loss in my refrigerator…per unit area k sm = 60 W/m·K k ins =.046 W/m·K h i = 5 W/m·K h o = 5 W/m·K L sm =.00635 m L ins =.0254 m

4. First, Find the R values

5. Then, find the rate of heat transfer, q Per Unit Area

6. Linear Interpolator The purpose of this Excel spreadsheet is to make it easier to incorporate data you need interpolated into your Excel spreadsheet calculations.

You put in the x and y values, and they appear in a neat box for you to use in your equations. You put in the x and y values, and they appear in a neat box for you to use in your equations.
