Optimality principles have been used, in a holistic approach, to describe flow processes in several important geosystems. Optimality principles refer to the state of a physical system that is ...

When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow of fluid through a duct ...

The word “thermodynamics” conjures up visions of complex mathematics to many people, even some with technical backgrounds. Yet, relatively simple formulas from thermodynamics can be used explain much ...
