This chapter discusses a number of flow conditions, where the authors treat the fluid as inviscid, i.e. they set its kinematic viscosity to zero. This assumption leads to many practical solutions in fluid mechanics. The hypothetical inviscid fluid is also known as ideal fluid. After defining the Euler equations, the chapter derives the important Bernoulli equation for a streamline. It connects pressure and flow velocity and is widely used in fluid mechanics. Later, the chapter derives more specific forms of the Bernoulli equation for specific flow types. The Bernoulli equation is an important tool in the evaluation of flow properties. In general, a fluid element will change position and shape in four different ways: translation, stretching (linear deformation), rotation, and shearing (angular deformation). For better visualization, the authors momentarily restrict themselves to planar (two‐dimensional) flow. The chapter explains the concepts of rotation, vorticity, and circulation.
