IIT JEE , AIEEE Forum - Physics , Thermal Physics - conic 3-d flow of heat

puneet

See, in a cone the area of the disc at any distance from the top is varying and also the rate is varying. So the integral is not a two dimensional integration. And thus the book says that the integration cannot be done. Now for the cylindrical flow the area is not varying it is a constant that is the face area of the cylinder. Ok?? Thus it is written as A.

Now good book for thermal physics, I always will make one comment use H.C Verma. It is the best book. Right ???

Take things easy and try to solve some easy questions so that it make your concepts strong before going for hard problems. Okay.

cheers
