The viscosity, specific heat, density, and thermal conductivity, respectively, of air are 1.44 x 10-5 kg/ m • s, 1.0059 x 103 J/ kg • K, l.5kg/ m3, and 0.0198W / m k. Calculate the heat transfer coefficient over the liver that would be needed to compute the freezing time. What temperature should have been used to read the air properties used in step 1?
