Consider the following grooves, each of width \(W\), that have been machined from a solid block of material.

(a) For each case obtain an expression for the view factor of the groove with respect to the surroundings outside the groove.

(b) For the \(V\) groove, obtain an expression for the view factor \(F_{12}\), where \(A_{1}\) and \(A_{2}\) are opposite surfaces.

(c) If \(H=1.3 \mathrm{~W}\) in the rectangular groove, what is the view factor \(F_{12}\) ?
