The mass or region outside the system is called the surroundings. 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.

The flow of compressible fluid such as air does not necessarily need to be treated as compressible since the density of a compressible fluid may still remain nearly constant during flow - especially flow at low speeds. Analysis External flow is the flow of an unbounded fluid over a surface such as a plate, a wire, or a pipe. Discussion The classical approach is easier and much more common in fluid cngel analysis. If you are a student using this Manual, you are using it without permission.Īnalysis A fluid flow during which the density of the fluid remains nearly constant is called incompressible flow. No part of this Manual may be reproduced, displayed or distributed in any form or by any means, electronic or otherwise, without the prior written permission of McGraw-Hill. Limited distribution permitted only to teachers and educators for course preparation. Analysis A fluid in direct contact with a solid surface sticks to the surface and there is no slip. Discussion Fluids in motion may have additional normal stresses, but when a fluid is at rest, the only normal stress is the pressure. In a fluid at rest, the normal stress is called pressure. Discussion As we shall see in later chapters, there different approximations are used in the analysis of fluid flows based on their classification.Īnalysis The classical approach is a macroscopic approach, based on 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. The real or imaginary surface that separates the system from its surroundings is called the boundary. 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.Īnalysis Stress is defined as force per unit area, and is determined by dividing the force by the area upon which it acts. This is known as the no-slip condition, and it is due to the viscosity of the fluid. 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. No other use or distribution of this Manual is permitted.
The region of flow in which the velocity gradients are significant and frictional effects are important is called the boundary layer.ĭiscussion It turns out that the Mach number is the critical parameter to determine whether the flow of a gas can be approximated as an incompressible flow.

The flow of liquids in a pipe is called open-channel flow if the pipe is partially filled with the liquid and there is cengl free surface, such as the flow of water in rivers and irrigation ditches. Discussion Descaegar opposite of steady flow is unsteady flow, which involves changes with time. The flow in a pipe or duct is internal flow if the fluid is completely bounded mecqnica solid surfaces.
