CE 230-Engineering Fluid Mechanics Lecture # 20-21 BERNOULLI EQUATION
Remember Euler’s equation Assumption made no losses
Let’s take l along a stream line call s (i.e. flow along a streamline) But Therefore
Assume steady flow and drop subscript But last term is Substituting back, dividing by γ (assuing incompressible fluid) and integrating wrt s we get
Bernoulli equation One form of BE is Note assumptions made No losses Flow along streamline Steady flow incompressible
