A slab 20 inch thick is made up of a material having a thermal conductivity of 33 Btu/hr-ft-°F. The temperature (°F) across the thickness of the wall is described by the function T(x) = 212 + 10x – x² when x is measured in inches from one face of the wall. Determine the heat flow in Watts/m2 at the point x = 13 inches.

3. A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5-kW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 kJ/h. There are 10 light bulbs in the room, each with a rating of 100 W. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 kJ/h. If the room air is to be maintained at a constant temperature of 210C, determine the number of window air-conditioning units required. draw a figure also, and explain each step by step solution.
