Using your results from Problem 3.8, find the heat flow at the base of the fin for the following conditions:k = 20 Btu/(h ft ?F)L = 2 in.

ho = 20 Btu/(h ft2 ?F)To = 200?FT?? = 80?FUse a grid spacing of 0.2 in.From Problem 3.8: Develop the control volume difference equation for one-dimensional steady conduction in a fin with variable cross-sectional area A(x) and perimeter P(x). The heat transfer coefficient from the fin to ambient is a constant ho and the fin tip is adiabatic.GIVENA fin with variable cross-sectional area and perimeter
