Why is the Nusselt number over flat plate for the constant heat flux is larger than the constant temperature condition?

The Nusselt number for the laminar and turbulent flow over a flat plate with constant heat flux is 36% and 4% larger than the constant temperature plate. For the laminar flow there is a...

Is the 'Mean Free Path' defined only for the gas phase? Is there any approximation for the mean free path of a liquid such as water?

In physics, the mean free path is the average distance traveled by a moving particle (such as an atom, a molecule, a photon) between successive impacts (collisions),[1] which modify its direction...
