Required information
Air flows in a pipe under fully developed conditions with an average velocity of 1.25 m/s and a temperature of 24°C. The
pipe's inner diameter is 4 cm, and its length is 4 m. The first half of the pipe is kept at a constant wall temperature of 100°C.
The second half of the pipe is subjected to a constant heat flux of 200 W. The properties of air at 80°C are p = 0.9994
kg/m³, k = 0.02953 W/m-K, v= 2.097 x 10-5 m²/s, cp=1008 J/kg-K, and Pr = 0.7154.
