Transcribed Image Text:

Air is flowing at a velocity of 3m/s perpendicular to a long pipe as shown in the figure. The outer diameter of the pipe is 6cm and the temperature at the outside surface of the pipe is maintained at 100C. The temperature of the air far from the tube is 30C. Surface temperature=100C Data for air: Nu = Kinematic Viscosity (v) = 18x10 m/s Thermal conductivity (k) = 0.03 W/mK Using the Nusselt number correlation hd k Air = 6cm 0.024. Re0.8 The rate of heat loss per unit length (W/m) from the pipe to the air (up to one decimal) is Air is flowing at a velocity of 3m/s perpendicular to a long pipe as shown in the figure.
