Principles of hydrodynamics
Hydrodynamics is concerned with the study and description of fluids in motion. The main emphasis is the teaching of the conservation laws of mass, energy and momentum.

Discharge
The flow from a tank can be regarded as both steady and transient. In the steady case the fill level, and thus the width of the jet, remains constant (e.g. discharge under a weir). When the tank is emptying during the discharge process, it is in what is referred to as the transient state.

Pipe flow
When flowing through a pipe the friction causes the pressure energy of the fluid to fall and the internal energy of the fluid to increase.
