Limited distribution permitted only to teachers and educators for course preparation. A flow in which density varies significantly is called compressible flow. Analysis The classical approach is a macroscopic approach, based edscargar experiments or analysis of the gross behavior of a fluid, without knowledge of individual molecules, whereas the statistical approach is a microscopic approach based on the average behavior of large groups of individual molecules.Дiscussion The classical approach is easier and much more common in fluid flow analysis. The real or imaginary surface that separates the system from its surroundings is called the boundary. The development of a boundary layer is caused by the no-slip condition. The region of flow in which the velocity gradients are significant and frictional effects are important is called the boundary layer.

Analysis When a fluid stream encounters a solid surface that is at rest, the fluid velocity assumes a value of zero at that surface. We are also to discuss whether wind-driven flows are forced or natural. The normal component of a force acting on a surface per unit area is called the normal stress, and the tangential component of a force acting on a surface per unit area is called shear stress. Analysis A fluid in direct contact with a solid surface sticks to the surface and there is no slip. The flow in a pipe or duct is internal flow if the fluid is completely bounded by solid surfaces. In natural flow, any fluid motion is caused by natural means such as the buoyancy effect that manifests itself as the rise of the warmer fluid and the fall of the cooler fluid.ДЄnalysis In forced flow, the fluid is forced to flow over a surface or in a tube by external means such as a pump or a fan. Discussion As we shall see in later chapters, there different approximations are used in the analysis decsargar fluid flows based on their classification. The flow caused by winds is natural flow for the earth, but it is forced flow for bodies subjected to the winds since for the body it makes no difference whether the air motion is caused by a fan or by the winds.Дiscussion As we shall see later, flow within a boundary layer is rotational individual fluid particles rotatewhile that outside the boundary layer is typically irrotational individual fluid particles move, but do not rotate.

Analysis A process is said to be steady if it involves no changes with time anywhere within the system or at the system boundaries. Analysis A system is defined as a quantity of matter or a region in space chosen for study. The velocity then varies from zero at the desargar to the freestream value sufficiently far from the surface.Дiscussion As seen here, the classification of forced vs. This Manual is being provided only to authorized professors and instructors for use in preparing for the classes using the affiliated textbook.
