Grashofs formula
WebFeb 11, 2024 · The necessary condition to satisfy Grashof’s Law is : S + L ≤ P + Q This condition is divided into two cases :- 1) S + L < P + Q 2) S + L = P + Q 1) Now lets see the first case i.e S + L < P + Q By fixing different … WebIn fluid mechanics, the Rayleigh number ( Ra, after Lord Rayleigh [1]) for a fluid is a dimensionless number associated with buoyancy -driven flow, also known as free (or natural) convection. [2] [3] [4] It characterises the fluid's flow regime: [5] a value in a certain lower range denotes laminar flow; a value in a higher range, turbulent flow.
