Bernoulli Equation (Energy Equation) for Fluid Flow 

Units: ft=foot, kg=kilogram, lb=pound, m=meter, N=Newton, s=second. Bernoulli (Energy) Equation for steady incompressible flow:
Mass density ρ can be found at mass density of liquids and gases. The steady state incompressible energy equation (also known as the Bernoulli equation) models a fluid moving from location 1 to location 2. The loss term h_{L} accounts for all minor (valves, elbows, etc.) and major (pipe friction) losses between 1 and 2. For Bernoulli applications, please see our Bernoulli Calculator with Applications.
