Topic: Heat Transfer
Given that Nu = Nusselt number, Re = Reynolds number, Pr = Prandtl number, Sh = Sherwood number, Sc = Schmidt number and Gr = Grashoff number. The function relationship for free convective heat transfer is given as,
- A. Nu = f(Gr, Pr)
- B. Sh = f(Sc, Gr)
- C. Nu = f(Re, Pr)
- D. Sh = f(Re, Sc)
Answer: A. Nu = f(Gr, Pr)
Explanation: For Free convection heat transfer, the relationship is Nu = f(Gr, Pr). For Forced convection heat transfer, it is Nu = f(Re, Pr).
