Explain frictional losses due to sudden expansion and contraction with necessary equations.
Write a short note on Creeping flow and Couette flow.
What is Reynolds's analogy?
Reynolds's analogy gives the interrelationship between fluid friction and newton’s law of viscosity.
The Reynolds analogy is given by,
Nu/RePr = St = Cf/2
Nu = Local Nusselt number, Re = Local Reynolds number, St = Local Stanton number, Pr = Prandtl number, Cf = Skin friction coefficient
