LET'S START THE JOURNEY

Every living creature in this earth understand the importance of Water and Air for their existence. Two-third of this landmass is covered with water. We can find it in deep oceans, underground the landmass, falling from the sky as raindrops and ice flakes, mountain zeniths covered with snow, in vapour form in the atmosphere we live, in fruits, vegetables, meats, and even in our body parts as body fluids or sweat and excretory products eliminated from the body. We are all aware of the basic requisite of oxygen for living beings to respire and survive, carbon dioxide necessary for the plants to synthesize their food, agin carbon dioxide being responsible for the well known Green House effect on the earth surface which helps trap the energy from sun in the form of heat etc.

Not only water but other such liquids as blood, alcohols, acids , glycerin, mercury, oil, gasoline etc are equally important liquids which we utilize for our needs both at the domestic level as well as industrial level. Similarly other equally important gases includes Nitrogen, Hydrogen, Refrigerant gases, methane, ethane, natural gas etc.

Hence every now and then, wherever and whenever we are, we are surrounded by one or the other kinds of liquids and gases. In technical jargon the liquids and gases collectively referred to as FLUIDS.

The most general distinction between a fluid and a solid is that a fluid is something which flows whereas a solid does not, or in other words fluids are something which flows.

Of course we are familiar with our high school concept of molecular arrangement of molecules and the level of packing being the basis of distinguishing the three states of matter. It is true and will always be. But, here in this course we would leap a step forward from this basic concept and describe the fluids in some different concepts , basis of which is again the molecular arrangemwnt only.

In a nutshell, what we are going to do in this basic course is to

1. Understand the physical, thermal and chemical properties of fluids, i.e. understanding the behaviour of fluid

2. Understanding the phenomenon of fluid flow and analysis of the associated phenomenal changes in properties and flow behaviour.

3. Learn the methods and techniques of measurement of all there properties and changes.

4. Distinguishing the fluids on the basis of its flow behaviour and characteristics.

and

5. Understanding the techniques of utilizing the energy content of fluids for fullfilling our needs.

The most striking feature of the course is to visualize and analyze some really wonderful, fascinating and mesmerizing phenomenon of the fluids.

It will surely be an interesting course and the scope of the subject is very very vast as what one can understand at this point.

Understanding the Course and its Contents

Mechanical Engineering covers a vast range of physical sciences occuring before us. Every state of matter, be it a Solid, Liquid or Gas is dealt with here and we aim to learn the Basic Physical Concepts ( 1st Year - Engineering Physics/Chemistry/Mechanics/&Mathematics), Physical Properties ( Mechanics of Materials/Strength of Materials/Material Science/ Fluid Mechanics), Thermal Properties (Thermodynamics/Heat & Mass Transfer/ Power Plant Engineering/ Refrigeration and Air Conditioning/ IC Engines), Applied Engineering ( Dynamics of Machines/ Kinematics of Machines/ Applied Thermodynamics/ Fluid Machines/ Gas Turbines and Propulsion Systems/ Production Engineering/ Manufacturing Processes/ Automobile Engineering) and then we have various Analysis & Simulation tools ( Softwares like AutoCAD, Catia, Pro-E, Ansys, Solidworks, CNC Part Programming, MATLAB, Numerical Methods, Computational Fluid Dynamics etc.)
