Air is flowing at a velocity of 3 m/s perpendicular to a long pipe as shown in the figure below. The outer diameter of the pipe is d = 6 cm and temperature at the outside surface of the pipe is maintained at 100 °C. The temperature of the air far from the tube is 30 °C. Data for air: Kinematic viscosity, ν = 18×10^-6 m²/s; Thermal conductivity, k = 0.03 W/(m·K). Using the Nusselt number correlation: Nu = (h d)/k = 0.024× Re^0.8, the rate of heat loss per unit length (W/m) from the pipe to air (up to one decimal place) is _______.
