More generally, the total potential energy is the sum of all the potential energies possible in a given situation. There is no new physics in the principle of conservation of mechanical energy. Everything follows from Newton's laws (refer back to the introduction of kinetic energy and potential...
Only the exhaust gases from the inhaled fresh gas mixture from the intake stroke, exhaust stroke, the heat energy of gasoline by burning conversion to push the piston movement of mechanical energy to drive the propeller rotation of work, the overall process is called a "loop". This is a ...
While −T:v→∘∇ represents a loss of mechanical energy, it produces internal energy within the volume V. If the flow is at rest v→=0, thus the balance of internal energy equation becomes: (2.97)∂∂t(ρε)+divq→=0 Substituting: (2.98)ε=cT and: (2.99)q→=−kgradT...
