use table A-15 kinematic viscosity

6. Consider a 2-m long smooth cylindrical pipe of 5 cm internal diameter, that is maintained at a constant surface temperature. Air flows through the tube at 0.5 m/s. Air enters the pipe at 20°C and leaves it at 60°C. Determine: (a) Is the flow laminar or turbulent? (b) Is the flow fully developed? (c) What Nu number correlation will you use to find h? Find Nu. (d) Find the convection heat transfer coefficient (h) inside the pipe (e) Find the temperature of the pipe surface. (35 points)
