Bernoulli’s Equation

Bernoulli’s equation is the most fundamental and generally utilized law within fluid flow. Bernoulli’s equation is fundamentally law in energy conservation. It is the total of kinetic/velocity energy and pressure in fluid flow is convertible each other and does not change its value. Mentioned diversely, for a ideal and constant flow of fluid that cannot compressible, the overall energy composed of datum energies, kinetic and pressure, is consistent at every position within the fluid.

p₁ + (V₁² / 2g) + Z₁ = p₂ + (V₂² / 2g) + Z₂

where:

Z = elevation of fluid (m)

V = Velocity of fluid (m/s)

p = pressure head of fluid (m) → pressure head is pressure (kg/m²) which is multiplied with specific volume (m³/kg)
