Nomenclature fluid mechanics

As we have seen, the above are variations of the mechanical energy equation. They are variously called the Bernoulli equation, the extended Bernoulli equation, or the engineering Bernoulli equation by writers of elementary fluid mechanics textbooks. Regardless of one s taste in nomenclature, Eq. (62) lies at the heart of nearly all practical engineering design problems. 

Table 1 shows the nomenclature in Equations (l)-(9). Equation (1), (2) and (3) are the governing equations of energy conservation for thermal process of mass conservation of fluid for hydrological process and of momentum conservation for mechanical process, respectively.
