A chicken house (20' x 10'x 8') with walls and roof with R-value = 5 hr oF ft2/BTU.

There are 2 wooden doors ( 80” x 36”) with an R-value of 2.5 hr ºF sq.ft/BTU.

The inside temperature is held at 35oC and the exterior temperature is 20oF.

There are 19 chickens in the house with a body temperature of 42oC that can be assumed to radiate as a sphere with a 14" diameter and a emissivity of 0.85.

PART A. Calculate the Heat generation by the chickens in BTU/hr.

Select one:

a. 99.05 BTU/hr

b. 1223 BTU/hr

c. 1040 BTU/hr

d. 1.209e4 BTU/hr

e. 3.440e4 BTU/hr

f. 3276 BTU/hr
