A uniform heat flux is maintained on the outer surface of the tube by an electric resistance heater wrapped around it. If the flow rate of the liquid is 0.15 m/s, find the required heat flux.

- A liquid of viscosity of 0.03 N s m2 is flowing under laminar conditions through a convergent, tapered tube for which the tube diameter changes linearly with length. The tube length is 0.50 m and its diameter varies from 0.01 m at the entrance to 0.005 m at the exit. Determine the pressure drop which is required to maintain the flow at a rate of 10-7 m3 s-1. The effect of kinetic energy due to the change in velocity in the tube may be neglected.

Would you expect the paint to exit the pipe as green paint or separate streams of blue and yellow paint? Explain. Repeat the problem if the paint were "thinned" so that it is only 10 times more viscous than water. Assume the density remains the same, and the temperature is 60°F. Classify the flow. Splitter Laminar Yellow Blue Laminar flow has mixing only by molecular diffusion. Turbulent flow has mixing due to large scale fluctuations. Reynolds number is a measure of whether flow is laminar or turbulent. Classification of viscous flow as laminar or turbulent dictates how the flow is analyzed.
