A plain carbon steel fin is 3cm long, 5mm thick, and 5cm deep. The temperature at the base of the fin is 40C while the surrounding air is 20C. h=50 W/m^2C.
A) how much heat does the fin transfer, and what is the fin effectiveness and fin efficiency?
B) if the fin was cut in half (1.5cm), is the new tip temperature the same as the temperature at that location when the fin was while? (Armenia hypothesis) is it true?
C) plot the temp distribution along the fin
i) convection from the tip (real case)
ii) ignore convection on the tip
iii) fin is infinitely long
