Grashof number signifies the ratio of
- Ainertia force to viscous force
- buoyancy force to viscous force
- Cbuoyancy force to inertia force
- Dinertia force to surface tension force
Explanation
The Grashof number is the natural-convection analogue of the Reynolds number — it represents the ratio of buoyancy forces to viscous forces acting on a fluid.
