The first law of thermodynamics states that changes in internal energy can be accounted for by heat losses: ΔE = Q – W, where ΔE is change in internal energy (Δ is the Greek letter "delta," and means "difference" here), Q is the amount of thermal energy t...
Such forms of energy include thermal energy dissipated because of fluid viscosity. The general form of Bernoulli’s equation has three terms in it, and it is broadly applicable. To understand it better, we will look at a number of specific situations that simplify and illustrate its use and ...
It is important to be aware that an assumption of the steady-state heat transfer cannot be used for modeling thermal processes of induction hardening because, according to the steady-state approach, the temperature would remain constant at a given point of heated component, for all time. However...

In a sound wave, density oscillations occur so fast that air molecules have no time to exchange thermal energy. Therefore sound waves can be considered adiabatic. If, in addition, the background temperature is constant (no hot jets), temperature is a function of density alone, and can be ...
