Question: Consider fully developed laminar flow with constant properties in a circular tube. Let there be heat transfer to or from the fluid at a constant rate per unit of tube length. Determine the Nusselt number if the effect of frictional heating (viscous mechanical energy dissipation) is included in the analysis. How does frictional heating affect the Nusselt number? What are the significant new parameters? Consider some numerical examples and discuss the results.
