Science of Fluid Mechanics: Distinction Between Solid and Fluid. Solid. Fluid. ▫ More Compact Structure. ▫ Attractive Forces between the molecules are larger. These lecture notes have been prepared as a first course in fluid mechanics up to Fluid mechanics concerns the study of the motion of fluids (in general liquids. A Textbook of Fluid Mechanics. By R. K. Bansal. About this book · Shop for Books on Google Play. Browse the world's largest eBookstore and start reading today.

Secondly, the book also demonstrates some possible modifications of the initial model which either make the model applicable in some special cases viscous or turbulent fluids or simplify it in accordance with peculiarity of a particular problem hydrostatics, two-dimensional flows, boundary layers, etc. The book explains theoretical concepts in two parts. The first part is dedicated to the derivation of the classical model of the perfect fluid. The second part of the book covers important modifications to the fluid model which account for calculations of momentum, force and the laws of energy conservation. Concepts in this section include the redefinition of the stress tensor in cases of viscous or turbulent flows and laminar and turbulent boundary layers. The text is supplemented by appropriate exercises and problems which may be used in practical classes. These additions serve to teach students how to work with complex systems governed by differential equations. Classical Fluid Mechanics is an ideal textbook for students undertaking semester courses on fluid physics and mechanics in undergraduate degree programs. This textbook primarily explains the construction of classical fluid model to readers in a holistic manner and the way it is constructed.

Determination of pipe diameter, determination of discharge, friction factor, critical velocity.

Module 7: Flow through orifices, mouthpieces, notches and weirs Lesson Orifices, vena contracta, Hydraulic coefficients Lesson Discharge losses, Time for emptying a tank Lesson External and internal Mouthpiece Lesson Types of notches, rectangular and triangular notches, rectangular weirs Lesson Numericals on orifice, mouthpiece, notch and weir Module 8: Measuring Instruments Lesson Venturimeter and pitot tube Lesson The surface tension of this liquid can be strengthened by adding a little glycerine to the solution.

An approximately rectangular soap film is thus formed.

You will have to exert a force to hold the straight wire in place. How is this force related to the surface tension? In this example, since the liquid film has two surfaces exposed to air, it is helpful to think of the problem as consisting of two separate liquid-gas films that lie next to one another.

Generally, this 2 multiplier will occur in a liquid film separating a gas from a gas e. A film separating a gas from a liquid e. The surface tension of a liquid is always a function of the solid or fluid with which the liquid is in contact.

If a value for surface tension is given in a table for oil, water, mercury, or whatever, and the contacting fluid is not specified, it is safe to assume that the contacting fluid is air. The value of 3 can be determined experimentally by stretching a film of fluid and measuring the required force as in Example 1.

Surfactunts are chemicals developed to change the surface tension of a liquid for a desired purpose. Detergents and wetting agents are familiar examples of liquids with surfactant properties.

When bubbles or films are made for experimental purposes, those made from pure water are very fragile and burst easily. Module 7: Flow through orifices, mouthpieces, notches and weirs Lesson Orifices, vena contracta, Hydraulic coefficients Lesson Discharge losses, Time for emptying a tank Lesson External and internal Mouthpiece Lesson Types of notches, rectangular and triangular notches, rectangular weirs Lesson Numericals on orifice, mouthpiece, notch and weir Module 8: Measuring Instruments Lesson Venturimeter and pitot tube Lesson Rotameter, Water level point gauge, hook gauge Module 9: Dimensional analysis Lesson
