    heat transfer from triangular fins

    Problem: Consider an aluminium alloy fin(k=180w/m-k) of triangular cross section with length l=5cm,base thickness b=1cm,and very large width w.The base of fin maintained at the temperature of T0=200 degrees centigrade. The fin is losing heat to the surrounding medium at T infinity=25 degrees with heat transfr coefficient of h=15 w/m^2-k. using the finite difference method withsix equally spaced nodes along the fin in X-direction,determine (a) the temperatures at the nodes,(b) the rate of heat transfer from the fin for w=1 meter and (c) the fin efficiency

    Nice, but we only help with your code. Simply dumping your assignment just doesn't cut it.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Q' fin= h((w*delta x)/cos teta )*((T0+2(T1+T2+T3+T4)+T5-10*Ta))
    Where h=15; w=1; delta x=0.01; teta=5.71 degrees;
    Since T0=200;
    T1=198.6;
    T2=197.1;
    T3=195.7;
    T4=194.3;
    T5=192 .9
    Ta=25;
    And the Q'fin =258.4
    I need c program of above equation
