A single glass window is 8' 0" * 5' 0". The outside temperature is 50 ° F and the inside temperature is 68 ° . How much heat is lost through the window?. Heat loss = constant * temperature difference * area (sq ft) Constant = 1.13 for window

Question

We can use the formula given to calculate the heat loss through the window:

Heat loss = constant * temperature difference * area

Here, the constant for the window is given as 1.13.

The temperature difference is:

68 °F - 50 °F = 18°F

The area of the window is:

8' 0" * 5' 0" = 40 sq ft

Substituting these values in the formula, we get:

Heat loss = 1.13 * 18 * 40
          = 813.6 Btu

Therefore, the best choice is A, 813.6 Btu.
