The flow in a pipe or duct is internal flow if the fluid is completely bounded by solid surfaces. Discussion 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 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.

Discussion There is no such thing as an inviscid fluid, since all fluids have viscosity. Discussion 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.

Limited distribution permitted only to teachers and educators for course preparation. Gunus 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. The normal component of a force acting on a gluidos 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.

We are also to discuss whether wind-driven flows are forced or natural. The mass or region outside the system is called the surroundings. No other use or distribution of this Manual is permitted.

Discussion As we shall see in later chapters, there different approximations are used in the analysis of fluid flows based on their classification. 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 fluid in direct contact with a solid surface sticks to the surface and there is no slip. The real or imaginary surface that separates the system from its surroundings is called the boundary.

Analysis External flow is the flow of an unbounded fluid over a surface such as fluiods plate, a wire, or a pipe. Discussion The opposite of steady flow is unsteady dr, which involves changes with time.

If you are a student using this Manual, you are using it without permission. By opening and using this Manual the user agrees to the following restrictions, and if the recipient does not agree yuns these restrictions, the Manual should be promptly returned unopened to McGraw-Hill: The velocity then varies from zero at the surface to the freestream value sufficiently far from the surface.

Discussion Fluids in motion may have additional normal stresses, but when a fluid is at rest, the tluidos normal stress is fkuidos pressure. Analysis 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.

This is known as the no-slip condition, and it is due to the viscosity of the fluid. If Ma is less than about 0. 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. Analysis When a fluid stream encounters a solid surface that is at rest, the fluid velocity assumes a value of zero at that surface.

This Manual is being provided only to authorized professors and instructors for use in preparing for the classes using the affiliated textbook. Discussion As seen here, the classification of forced vs. 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.

The development of a boundary layer is caused by the no-slip condition. The flow of liquids in a pipe is called open-channel flow if the pipe is partially filled with the liquid and there is a free surface, such as the flow of water in rivers and irrigation ditches. Analysis Stress is defined as force per unit area, and is determined by dividing the force by the area upon which it acts. This has been a source of confusion for students for many years.

The region of flow in which the velocity gradients are significant and frictional effects are important is called fluidoss boundary layer. A flow in which density varies significantly is called compressible flow. Discussion The classical approach is easier and much more common in fluid yunud analysis. Analysis A system is defined as a quantity of matter or a region in space chosen for study.

In a fluid at rest, the normal stress is called pressure. This Manual may not be sold and may not be distributed to or used by any student or other third party. Analysis Cenhel 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.

Analysis A fluicos flow during which the density of the fluid remains nearly constant is called incompressible flow.
