Heat Transfer - Engineering

Q1:

Reynold's analogy states that

A Nst α f

B Nst α NRe

C NNu α f

D NRe α f

ANS:A - Nst α f

Reynolds analogy is a concept in fluid mechanics that relates the friction factor (f) in a flow system to the heat transfer characteristics of the flow. It states that: Nusselt number (Nu) is proportional to Reynolds number (Re) to the power of 1/2. So, the correct statement related to Reynolds analogy would be: NRe α f This indicates that the Reynolds number (Re) is proportional to the friction factor (f).
