     CE010 303: FLUID MECHANICS

Teaching scheme: Credits: 4

    2 hours lecture and 2 hours tutorial per week

Objective

    ; This course gives an introduction to the fundamentals of fluid flow and its

    behavior so as to equip the students to learn related subjects and its application

    in the day to day life in a very effective manner.

Module 1(12hours)

    Properties of fluids: Definition and Units- Mass density, Specific weight,

    Viscosity Classification of fluids Ideal and real fluids, Newtonian and non

    Newtonian fluids.

    Fluid pressure Atmospheric, Absolute, Gauge and Vacuum pressure,

    Measurement of pressure Piezometer, manometer, mechanical gauges.

    Total pressure and centre of pressure on a submerged lamina, pressure on a

    submerged curved surface pressure on lock gates, pressure on gravity dams. Module 2(12hours)

    Buoyancy Centre of buoyancy Metacentre Stability of floating and

    submerged bodies Determination of metacentric height Analytical &

    experimental methods.

    Kinematics of fluids : Methods of describing fluid motion:Legrangian& Eulerian

    methods-Types of flow Streamline, Path line and Streak line, Velocity potential

    function, Stream function, Circulation and Vorticity, Laplace’s Differential

    equation in rectangular co-ordinates for two dimensional irrotational flow.

    Flow Net Orthogonality of stream lines and equipotential lines.

    Stream tube continuity equation for one dimensional flow.

Module 3(12hours)

    Forces influencing motion Energy of fluids, Euler’s equation, statement and

    derivation of Bernoulli’s equation and assumptions made.

    Applications of Bernoulli’s equation Venturi meter, Orifice meter, Pitot tube.

    Orifices and Mouth Pieces Different types of orifices,flow over a sharp edged

    orifice- flow through large rectangular orifice- flow through submerged orifice-

    Hydraulic Coefficients-External and internal mouthpiece.

    Notches and weirs Rectangular, triangular, trapezoidal notches, Cippoletti weir,

    submerged weir, broad crested weir.

Module 4(12hours)

    Flow through pipes: Two types of flow-Laminar and Turbulent flow

    Reynold’s experiment, loss of head due to friction, Darcy – Weisbach equation,

    Other energy losses in pipes.

    Hydraulic Gradient and Total Energy Lines: Flow through long pipes Pipes

    in series and parallel, Siphon, Transmission of power through pipes nozzle

    diameter for maximum power transmission.

    Laminar Flow in circular pipes: Hagen poiseuille equation.

    Turbulent flow through pipes:Establishment of flow in pipes-hydro-

    dynamically smooth and rough boundary, Velocity distribution for turbulent flow

    in pipes.

    Drag and lift for immersed bodies:

Module 5(12hours)

    Dimensional Analysis and Model studies: Units and dimensions of physical

    quantities, Dimensional Homogeneity of formulae and its application to common

    fluid flow problems, Dimensional Analysis-Rayleigh’s method, Buckingham’s

    method. Derivations of dimensionless parameters, Froude’s, Reynold’s, Webber,

    Mach numbers.
