Copper fins, 1.7 cm long and 1.8 mm in diameter, are attached to a base plate at 75∘C. A fan blows air through and around this fins at 15∘C providing an average convection coefficient of 22 W m−2 K−1. Estimate the heat dissipated through each of these fins, in milliwatt (mW). Assume negligible heat transfer though the tips. The conductivity of copper may be taken to be 400 W m−1 K−1.
