WebThe Prandtl number is a useful intrinsic property, which can vary considerably depending on a substance. For instance, for liquid metals due to electron contribution to thermal conductivity. Usually, the Prandtl number is around for gases, around for water at 25 C, and can be higher for liquified noble gases [ 2 ].
