The energy per unit mass contained in a system is comprised of three parts: internal, kinetic and potential. The internal energy per unit mass of the fluid is simply denoted here as e.

In a Newtonian fluid, energy is exchanged between kinetic, potential and internal forms through various identifiable processes. Recall that a fluid is in fact made of molecules (section 1.2).

This term is approximated at the center of the tiny control volume, i.e., The conservation of mass equation (Eq. 9-2) thus becomes Dividing Finally, we apply the definition of the divergence of a

This is valid for a system and can be written in control-volume form, but there are al-most no practical applications in fluid mechanics except to analyze flow-loss details (see Sec. 9.5).

Fluid mechanics deals with the behaviour of liquids and gases in rest or in motion. Numerous intriguing questions can be answered using fundamental concepts of fluid mechanics.

Since the change in momentum is the same for both halves of the flow, we need only consider the vector diagram for one half. The initial velocity is v1 and the bucket velocity u1 is in the same direction.
