Unformatted text preview: wall. • Write a Matlab mfile to evaluate the rate of heat loss per unit area. The mfile should contain variables used in the algebraic expressions. The variables should be assigned the corresponding numerical values. The variables should then be employed in an equation which corresponds to the algebraic equations you derived. • Now assume that a blizzard is blowing outside the house which raises the convection heat transfer coefficient on the outside to 300 = o h W/m 2 ·K. W. What is the corresponding rate of heat loss per unit area? Evaluate using your mfile by changing the one value. Does the value change significantly? Is the house well insulated? • What is the element in the wall which has the largest resistance to heat transfer? Please answer quantitatively. Note: Turn in a properly commented mfile along with the solutions....
