Question

In natural convection heat transfer, the parameter

a) Nusselt Number
b) Rayleigh Number
c) Grashof Number
c) Lewis Number

Answer 1

correct answer is option c i.e Grashof Number

Step-by-step explanation:

The Grashof number is a dimensionless number, which is named after renowned scientist Franz Grashof. The Grashof quantity is defined as the proportion of the buoyant force to viscous force performing on a fluid in a pace boundary layer.

Its function in natural convection is more or less the same as that of Reynolds's number in compelled convection.
