In free convection heat transfer, Nusselt number is function of
A
Grashoff number and Reynold number
B
Grashoff number and Prandtl number
C
Prandtl number and Reynold number
D
Grashoff number, Prandtl number and Reynold number
Correct Answer: Grashoff number and Prandtl number
In free convection heat transfer, Nusselt number is function of Grashoff number and Prandtl numberthe Nusselt number (Nu) is the ratio of convective to conductive heat transfer at a boundary in a fluid.
