a= 1044 * .13 * .05 = 6.786 b= 64 * .05 = 3.2 c= 1792 * .13*.05 = 11.648 d= 1645 * .05 =82. 25 6.786 + 3.2 + 11.648 + 82.25 = 103.884 Where did you get this formula, please?
So if I did the corrections, then it would equal 18.434 and the second calculation would equal 6.786 .18434/.06786=.270 KJ Correct, Better or still wrong
