In the text we investigated the parabolic velocity profile associated with the laminar flow of fluid through a circular pipe. If the pipe wall is heated in such a way that the wall heat flux is independent of the axial position (e. g. via a resistance heating element wrapped around the pipe at a constant pitch), the temperature profile within the fluid is given by
T=Ts-Co(3Rp^2/16 - r^2/4 + r^4/16Rp^2) where T is the temperature of the pipe surface and Co is a constant. ( Rp is another variable)
!. What are the dimensions for Co.
2. Sketch the temperature profile as a function of r for constant axial position
3. Compare and discuss the shapes of the temperature and velocity profiles
4. Calculate the diffusive heat flux per unit area to the pipe wall.

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
