When viscous dissipation is included, Equation
Chapter 8, Problem 8.10(choose chapter or problem)
When viscous dissipation is included, Equation 8.48(multiplied by ?cp) becomesThis problem explores the importance of viscous dissi-pation. The conditions under consideration are laminar,fully developed flow in a circular pipe, with ugiven byEquation 8.15.(a) By integrating the left-hand side over a section of apipe of length Land radius ro, show that this termyields the right-hand side of Equation 8.34.(b) Integrate the viscous dissipation term over the samevolume.(c) Find the temperature rise caused by viscous dissi-pation by equating the two terms calculated above.Use the same conditions as in 8.9.
