//Variable declaration:
L = 3.0*0.0254 //Height of fin (m)
t = 1.0*0.0254 //Thickness of fin (m)
h = 15.0 //Heat transfer coefficient (W/m^2.K)
k = 300.0 //Thermal conductivity (W/m.K)
//Calculation:
Lc = L + t/2.0 //Corrected height of fin (m)
Ap = Lc*t //Profile area of fin (m^2)
x = sqrt((Lc**3*h)/(k*Ap)) //x-coordinate of figure 17.3
//From figure 17.3:
nf = 98.0 //Fin efficiency
//Result:
printf("The fin efficiency is : %f %%",nf)
