Question: a rectangular fin k170 wmk length 10mm thickness2mm is exposed...

Question details

A rectangular fin K=170 (W/m.k), length= 10mm, thickness=2mm is exposed to a medium of uniform convective coefficient of h=150 (W/m^2.k) at a temperature

T=30 °C. IF an adiabatic fin approximation is assumed. The width w>>t and the temperature at the base of the fin is Tb = 120°C.

  1. Calculate the fin heat transfer rate per unit width
  2. Calculate the fin effectiveness,
  3. Calculate the fin efficiency
  4. Calculate the fin tip temperature
