i read in class 11and in class we have been taught in 3-d flow of heat tht we cannot calculate heat current for a cone because of its pointed nature since temperature difference at the point will be indeterminate..hence cannot apply integration ..i cud not understand this part...plzz help me out coz i knew tht wen anything varies we do integration...can u suggest me gud books which will help to strengthen my concept on thermal physics?again for cylindrical flow of heat we write H=-KAdt/dr...but A is also varying..then why dunt we write dA?my concept is not strong..plzz help me..
