Required information Air flows in a pipe under fully developed conditions with an average velocity of 1.25 m/s and a temperature of 24C. 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 100C. The second half of the pipe is subjected to a constant heat flux of 200 W. The properties of air at 80C are p = 0.9994 kg/m, k = 0.02953 W/m-K, v= 2.097 x 10-5 m/s, cp= 1008 J/kg-K, and Pr = 0.7154. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air 1.25 m/s 2m T = 100C D=4 cm 2m Q = 200 W Determine the air temperature at the 2 m length. The air temperature at the 2 m length is 50.517 C.
