Problem 71E

A picture window has dimensions of 1.40 m X 2.50 m and is made of glass 5.20 mm thick. On a winter day, the temperature of the outside surface of the glass is - 20.0o C, while the temperature of the inside surface is a comfortable 19.5o C. (a) At what rate is heat being lost through the window by conduction? (b) At what rate would heat be lost through the window if you covered it with a 0.750-mm-thick layer of paper (thermal conductivity 0.0500 W/m ? K)?

Step-by-Step Solution:

Solution to 71E Step 1 Power emitted by the bulb=150W Temperature of incandescent bulb=2450K Emissivity =0.35
