State Bernoulli theorem.
What is Reynold’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
