A homeowner has insulated a 1750ft2 attic with R30 insulation. The R value commonly used in home insulation has been defined so that R = x/k (thickness, (x), divided by conductivity, (k), in units of hr*ft2*oF/Btu). On a certain day, the inner temperature of the insulation is 65 oF and the outer temperature of the insulation is 30 oF. What is the heat loss through the attic insulation?
