Q1 Heat conduction in rectangular fin 20 Points See the picture: L Out by transfer to air stream 12B x Az W In by Out by conduction conduction Let dx = dz Wall temperature known to be Tw Q1.1 Rectangular fin (a) 10 Points Use the new data as shown, find the heat loss: Q.LOSS (in Watts) from the fin! You can use the formula in picture! The definition of "N" is given in picture! Note we have use x =z in the coordinates!
