Seminar 4 illustrated the use of the Matlab program fin_efficiency.m, which, as the name suggests, calculates the fin efficiency (plus temperature distribution) for a thin fin having an adiabatic tip. (The program fin_efficiency.m plus the supporting Matlab program mnhf_thomas.m can be found in the eClass/Seminar exercises folder titled "Week of Jan. 31 -- supplemental material".) Following the procedure outlined in the seminar, run fin_efficiency.m then answer the question below: (a) When the fin efficiency is 90%, what is the non-dimensional fin tip temperature, (T..-T00) (T.- Too)? (b) When the fin efficiency is 70%, what is the non-dimensional fin tip temperature, (Too -Too) (T. - Too)? (c) When the fin efficiency is 20%, what is the non-dimensional fin tip temperature, (TH2-Too)/(T. - Too)
