Simplified bernoulli equation
WebbSimplified Bernoulli Equation. Bernoulli’s equation results from the application of the general energy equation and the first law of thermodynamics to a steady flow system in which no work is done on or by the fluid, no heat is transferred to or from the fluid, and no change occurs in the internal energy (i.e., no temperature change) of the ...
