FLUID MECHANICS Fluid Mechanics is that branch of science  which deals with behaviour of  the fluids at rest as well as in motion
Fluid mechanics can we divided into 3 divisions: ,[object Object],[object Object],[object Object]
What is Fluid ? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
For  all practical purposes , the liquids and solids can be regarded as incompressible.This means that pressure and temperature have practically no effect on them.Eg Water, Kerosene,petrol etc. ,[object Object]

After that you washed your face at the sink. The water which comes  at your tap is fluid and has come through the piping system which also comes under fluid mechanics.
After that you decided to have your breakfast.  The coolant moving inside the small pipes at the back of your refrigerator, and the air circulating inside it are both fluids.
 
After finishing your breakfast,  You decided to do some cleaning before heading to the school. Proper suction of air and filtering the dust requires the knowledge of Fluid Mechanics.
After that you turned on your T.V to get the morning news. Nothing good, war again
UNMANNED AIR VEHICLE USED BY US ARMY IN AFGHANISTAN
MISSILE AERODYNAMICS
Now it’s the time to go to college, otherwise you will get late ,[object Object]
Before your class you went to PC lab and took a print out of your assignment. Inkjet printing also involves fluid mechanics.
Knowledge of Fluid Mechanics is essential for proper design of Ships.
Otherwise without the proper knowledge of fluid mechanics, What will happen
In this subject, topic on  Model Studies is there which is very important for civil engineers. ,[object Object]
Significance of Fluid Mechanics ,[object Object],[object Object],[object Object],[object Object]
Ideal Fluid: A fluid is said to be ideal if it is assumed to be both incompressible and inviscid  (non-viscous). ,[object Object],[object Object]
Real Fluid: Practical Fluid have surface tension, viscosity and compressibility. ,[object Object]
Density (  ) ,[object Object],[object Object],[object Object]
Specific Gravity(s): ,[object Object],[object Object]
It is dimensionless quantity. ,[object Object],[object Object]
Specific Volume: Represents the volume per unit mass of fluid. ,[object Object],[object Object],[object Object],[object Object]
Viscosity: It is the property of the fluid by virue of which it offers resistance to shear or angular deformation. ,[object Object],[object Object]
Newton’s Law of Viscosity ,[object Object],[object Object],[object Object]
Following Observations can be made from Newton’s viscosity Equation: ,[object Object],[object Object]
