Hot air flows through a metal pipe with a diameter of 0.15 m at a speed of 0.05 kg/s. Hot The air enters at 103 C and leaves the 5 m pipe at 77 C. Outdoor temperature at 0C The heat transfer coefficient between the outer surface of the pipe and the pipe is 6 W/m2 .K. heat from this pipe loss (W/m2) in the light of the given, write down the necessary assumptions. (For air k= 0.030 W/m.K, = 208.2 x10-7 N.s/m2 , Npr = 0.70)
