Question

Why does turbulent rivers have gh dissolved oxygen content? Can you draw analogy from any laboratory practice?

Answer 1

In turbulent flow, one can estimate the Nusselt number using the analogy between heat and momentum transfer (Colburn analogy). This analogy relates the Nusselt number to the coefficient of friction, Cf as

(a) Nu = 0.5 Cf, Re Pr1/3

(b) Nu = 0.5 CfRe Pr2/3

(c) Nu = CfRe Pr1/3

(d) Nu = Cf Re Pr2/3

(e) Nu = CfRel/2Pr1/3

Answer 2

Almost every water that is found in the surface of the earth contain dissolved oxygen in them. River waters are no sufficient different from them. River water contains a lot of dissolved oxygen in them. But compared to the other sources of water like the underground water which comes through the tap, river water contains a lot more of the dissolved oxygen in them. Hope this answers helps you.
