air is flowing inside of a pipe with radius=0.4 meters at a mass velocity of 29.4 kg/s*m2 at 322 K, with the walls of the pipe at 300 K. At the conditions of the experiment, the viscosity of air is 1.984 x 10-5 Pa*s, the density of air is 1.22 kg/m3, the heat capacity is 1 kJ/kg*K, and the thermal conductivity is 0.025 W/m*K. Determine the rate of heat loss by air per meter of duct.
