Air stream with m = 0.05 kg/s passes in a metal tube with D=0.15 m. The air moves at 103 °C to the tube. After a while (after 5 m distance in the tube), it's temperature decreases to 77 °C. The ambient temperature is 0 °C. The heat transfer coefficient between the ambient air and outer surface of the pipe is 6 W/m²K. a) Determine the heat loss from the pipe over length L. b) Calculate the heat flux when x=L. @363K,air →c, =1010J/kgK,@350K, air →μ=208×10 Ns / m², k = 0.03W/mK, Pr=0.7 Air stream with m = 0.05 kg/s passes in a metal tube with D=0.15 m.
