6. Fluid in a round tube of radius R has a temperature profile of T = To(1+ ) and a velocity profile p2 2R2 = uo(1 – ). (a) Calculate the mixed mean temperature. (b) Calculate the temperature you would get if you stopped the flow, dumped all the fluid in the tube into a cup, and mixed it until the temperature was uniform. (c) Explain why your answers to (a) and (b) are not the same.

Q.3 A firm produces frozen fruits and vegetables, and a venturimeter is used in this process.In a certain step of the process, the cherries are introduced to the cold air stream at -12oC with a 3 in. pipe connected vertically to the throat of the venturimeter. Venturimeter is connected to a pipe 4 in. in diameter. If the air velocity in the throat is 5 times the terminal velocity of the cherries and the ratio of throat/pipe diameter is 0.6, what should be the flow rate of air? Assume that the density of cherries is 1200 kg/m3 and the average diameters are 12 mm. What should be the lay-out of the pipeline between venturimeter and freeze-dryer to prevent the striking of the cherries to the walls? Is there any settling possibility of the cherries at the exit of the venturimeter?
Carbon dioxide is being pumped through a smooth pipe at the rate of 3×10-4 kmol/sec for a distance of 2000 m. Ifthe line is isothermal at 323.15 K and the pressure at the entry point is 750 ×103 Pa and at the exit point is 430×103 Pa, what diameter should the pipe has to ensure that the CO2 will be delivered to the end point with the pressure drop experienced. The viscosity of CO2 at 323.15 K is 1.45×10-5kg/m.s. One trial is sufficient given you tell us how you will proceed to achieve an accurate diameter estimate. Hint: for your initial guess, use D in the range of 0.01-0.02 m.
