Mechanical Engineering

Hot air flows with a mass flow rate of 0.05 kg/s through aninsulated square duct with side of 0.15m, the hot air enters at 103oC and after a distance of 5m, cools to 85oC. The heat transfer coefficient between the duct outersurface and the ambient air (Tair = 0 oC) is6 W/m2 K.

Calculate the heat transfer coefficient between hot air and ductinner wall.

Air Cp = 1.011 KJ/kg K; air k = 0.0306 W/m K, air viscosity =211.7*10 -7 Ns/m2; air Pr = 0.698
