Air flows through a pipe that 10-cm in diameter, and 6.75-m in length. The air moves through the pipe at an average velocity of 2.5 m/s, and in doing so its temperature drops 20°C as it passes through the pipe (from the inlet through to the outlet). Take the properties of air as follows: Cp-1007 J/kgK, k = 0.02551 W/m-K, p= 1.184 kg/m³, v= 1.56x10-5 m²/s, and Pr = 0.7296 1) Reynolds number [Select] 2) Nu [Select] 3) Q [Select]
