- 4. 4 In thermodynamics analysis, it is often helpful to consider the various forms of energy that make up the total energy of a system in two groups: 1. Macroscopic 2. Microscopic Forms of Energy
- 5. 5 Forms of Energy The macroscopic energy of a system is related to motion and the influence of some external effects such as gravity, magnetism, electricity, and surface tension. The energy that a system possesses as a result of its motion relative to some reference frame is called kinetic energy (KE). The energy that a system possesses as a result in gravitational field is called potential energy (PE). PE = mgz The total energy of a system consist of the kinetic, potential, and internal energies as E = U + KE + PE = U + mgz +

- 8. 8 Mechanical Energy The Mechanical Energy can be defined as the form of energy that can be converted in to mechanical work completely and directly by an ideal mechanical device such as ideal turbine. Potential and kinetic energies are the familiar forms of mechanical energy.
