Question: Forced convection example Air flows at 1 0 m / sec through a smooth round tube ( 3 cm diameter by 1 2 m long

Forced convection example
Air flows at 10 m/sec through a smooth round tube (3 cm diameter by 12 m long) with a
uniform tube wall temperature of 500\deg C. If the air enters at 100\deg C, at what temperature
does it exit from the tube?
