Question 5 5 pts Air flows through a pipe that is 17-cm in diameter, and 4.5-m in length. The air moves through the pipe at an average velocity of 3.25 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=1027 J/kgK, k = 0.025 W/m-K, p= 1.2 kg/m³, v= 1.56x10-5 m²/s, and Pr = 0.7 1) Reynolds number [Select] 2) Nu [Select] 3) Q [Select] Question 6 1 pts 4) Following from the previous question, if the air temperature at the inlet is 40°C. What was the film temperature (in degrees celcius) used to determine the air properties?
