How is the heat transfer rate through a window found?

Q = U-Value × TD × Area
Q = Area ÷ U-Value × TD
Q = TD ÷ Area × U-Value
Q = U-Value × Area ÷ TD

The correct answer is: Q = U-Value × TD × Area

The correct answer is A. The heat transfer rate through a window is found by using the formula Q = U-Value × TD × Area. The U-Value represents the thermal conductivity of the window material, TD (temperature difference) indicates the temperature difference between the inside and outside of the window, and Area refers to the surface area of the window through which heat is being transferred. By multiplying these three factors together, you can calculate the heat transfer rate accurately. Options B, C, and D are incorrect because they are not utilizing the correct relationship between the U-Value, temperature difference, and area in the formula for determining the heat transfer rate through a window.
