Unformatted text preview: 5-28C Solution We are to define and discuss static, dynamic, and hydrostatic pressure. Analysis Static pressure P is the actual pressure of the fluid . Dynamic pressure V 2 /2 is the pressure rise when the fluid in motion is brought to a stop isentropically . Hydrostatic pressure gz is not pressure in a real sense since its value depends on the reference level selected, and it accounts for the effects of fluid weight on pressure . The sum of static, dynamic, and hydrostatic pressures is constant when flow is steady and incompressible, and when frictional effects are negligible. ME 330 Fluid Mechanics Spring 2007 Department of Engineering Western Kentucky University Discussion The incompressible Bernoulli equation states that the sum of these three pressures is constant along a streamline; this approximation is valid only for steady and incompressible flow with negligible frictional effects....
