A straight fin of rectangular cross section fabricated from an aluminum alloy (k= 185w/m*k) has a base thickness of t=3mm and a length of L= 15mm. Its base temperature is Tb= 100C, and it is exposed to a fluid for which T?= 20C and h= 50w/m^2*k.

A) For the forgoing conditions and a fin unit width, calculate the fin heat rate, efficiency, and effectiveness.

B) Compare the foregoing results with those for a fin fabricated from pure copper (k= 400w/m*k)
