The strategy for solving most problems in inviscid,incompressible flow is as follows: 1.Obtain the velocity field from the governing equations. 2.Once the velocity field is known,obtain the corresponding pressure field from Bernoulli's equation.Copyright by Dr. Zheyan Jin Chapter 3 Fundamentals of Chapter 3 Fundamentals of Inviscid Inviscid, Incompressible Flow , Incompressible Flow 3.1 Bernoulli’s Equation The strategy for solving most problems in inviscid, incompressible flow is as follows: The physical significance: 1.
