However, it is a useful concept in fluid mechanics since fluids are often forced into and out of control volumes in practice. Analysis A flowing fluid possesses flow energy, which is the energy needed to push a fluid into or out of a control volume, in addition to the forms of energy possessed by a non-flowing fluid.
The total energy of a non-flowing fluid consists of internal and potential energies. If the fluid is moving as a rigid body, but not flowing, it may also have kinetic energy e. The total energy of a flowing fluid consists of internal, kinetic, potential, and flow energies. Discussion Flow energy is not to be confused with kinetic energy, even though both are zero when the fluid is at rest. Analysis The macroscopic forms of energy are those a system possesses as a whole with respect to some outside reference frame.
The microscopic forms of energy, on the other hand, are those related to the molecular structure of a system and the degree of the molecular activity, and are independent of outside reference frames.
Discussion We mostly deal with macroscopic forms of energy in fluid mechanics. Analysis The sum of all forms of the energy a system possesses is called total energy.
In the absence of magnetic, electrical, and surface tension effects, the total energy of a system consists of the kinetic, potential, and internal energies. Discussion a All three constituents of total energy kinetic, potential, and internal need to be considered in an analysis of general fluid flow. Chapter 2 Properties of Fluids C Solution We are to list the forms of energy that contribute to the internal energy of a system.
Analysis The internal energy of a system is made up of sensible, latent, chemical, and nuclear energies. The sensible internal energy is due to translational, rotational, and vibrational effects.
Discussion We deal with the flow of a single phase fluid in most problems in this textbook; therefore, latent, chemical, and nuclear energies do not need to be considered. Analysis Thermal energy is the sensible and latent forms of internal energy.
It does not include chemical or nuclear forms of energy. In common terminology, thermal energy is referred to as heat. However, like work, heat is not a property, whereas thermal energy is a property. Analysis Using specific heat values at the average temperature, the changes in the specific internal energy of ideal gases can be determined from u c v,avg T.
For incompressible substances, cp cv c and u c avg T. Discussion If the fluid can be treated as neither incompressible nor an ideal gas, property tables must be used. Analysis Using specific heat values at the average temperature, the changes in specific enthalpy of ideal gases can be determined from h c p,avg T. For incompressible substances, cp cv c and h u vP c avg T vP.
