Choose the right answer
a) Nusselt number
b) Rayleigh number
c) Grashof number
d) Lewis number

Answer 1

correct option is c

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.
