Question

Determine the total heat loss from a shed (10’x10’x10’) being heated by a small wood stove.

The internal temperature of the shed is 70^oF and the outdoor temperature is 21^oF.

The shed walls are made up of 1.5 inch of plywood (0.94 per 3/4") and 1 inch of polystyrene (R=5 per 1"), while the roof made of insulated corrugated metal has a combined U value of 0.2 BTU/oF ft2 hr. There are two glass windows measuring 2’ x 3’ with a R-value of 1.0 oF ft2 hr/BTU. as well as 1 wooden door ( 80” x 36”) with an R-value of 5 oF ft2 hr/BTU.

Assume there is no heat loss through the concrete foundation.

Select one:

a. 4090.932

b. 4384.932

c. 4318.84

d. 3404.93

e. 3828.84
