Syllabus for Civil Engineering IInd year, Arybhatta Knowledge University ,Bihar


207 FLUID MECHANICS

INTRODUCTION: Concept of continuum, difference between fluid mechanics and solid mechanics, brief history of classical hydraulics, hydrodynamics and fluid mechanics.

Characteristics properties of fluids- ideal and real fluids, Newtonian and non-Newtonian fluids viscosity, surface tension, capillarity compressibility, fluids statics and buoyancy
Fluid kinematics- Stream lines, path lines, streak lines, velocity potential and stream functions, laminar and turbulent flows, steady and unsteady flows, rotational, irrotational motion-circulation, vorticity, velocity and acceleration.

FLUID DYNAMICS: Conservation of mass, principle of momentum and energy, moment of momentum, equation of motion, Euler’s equation, Introduction to Navier’s-Stokes equation, energy equation, hydraulic and energy gradients.

LAMINAR FLOW: Flow through pipes, frictional and other losses.

TURBULENT FLOW: Fully developed flows, boundary layer theory, rough and smooth pipe flows.

DIMENSIONAL ANALYSIS: Similitude of fluid flows, Hydraulics modeling, non-dimensional parameters (Reynolds, Fronde, Euler, Weber and Mach Numbers)

FLOW MEASUREMENT: Piezometer, manometers, pressure gauges, pilot tube, orifices, noticlers and weirs, orifice meter, venturimeter, forces on immersed bodies- drag and lift, asfoil section fluid mechanics, dynamic force exerted by fluid on fixed and moving vanes, racial flow over curved vanes, applications to hydraulic turbine blades, impulse and reaction turbines, reciprocating and centrifugal pumps, pressure due to deviated flow in pipes, jet propulsions.
