Answer:
300 Btu per hour
Explanation:
given data
area = 100-square foot
thick = 12 inch
R value at 12 = 1.89
R value at 4 = 14.8
inside temperature = 65 degrees F
outside temperature = 15 degrees F
to find out
How many Btu per hour
solution
we get here How many Btu per hour that is express as
Btu per hour =
............1
put here value we get
Btu per hour = ![\frac{100(65-15)}{1.89+14.8}](https://tex.z-dn.net/?f=%5Cfrac%7B100%2865-15%29%7D%7B1.89%2B14.8%7D)
Btu per hour = 299.580
so Btu per hour is 300 Btu per hour
