FLUID MECHANICS AND HYDRAULIC MACHINERY
UNIT I
Fluid statics : Dimensions and units: physical properties of fluids- specific gravity, viscosity ,surface
tension- vapor pressure and their influence on fluid motion- atmospheric, gauge and vacuum pressure –
measurement of pressure- Piezometer, U-tube and differential manometers.
UNIT II
Fluid kinematics : Stream line, path line and streak lines and stream tubes, classification of flows-steady
& unsteady, uniform, non uniform, laminar, turbulent, rotational, and irrotational flows-equation of continuity
for one dimensional flow.
Fluid dynamics : Surface and body forces –Euler’s and Bernoulli’s equations for flow along a stream line,
momentum equation and its application on force on pipe bend.
UNIT III
Closed conduit flow: Reynold’s experiment- Darcy Weisbach equation- Minor losses in pipes- pipes in
series and pipes in parallel- total energy line-hydraulic gradient line.
Measurement of flow: pilot tube, venturimeter, and orifice meter, Flow nozzle, Turbine flow meter (Ref.4)
UNIT IV
Basics of turbo machinery : Hydrodynamic force of jets on stationary and moving flat, inclined, and
curved vanes, jet striking centrally and at tip, velocity diagrams, work done and efficiency, flow over radial
vanes.
UNIT V
Hydroelectric power stations : Elements of hydro electric power station-types-concept of pumped
storage plants-storage requirements, mass curve (explanation only) ,estimation of power developed from a
given catchment area; heads and efficiencies.
UNIT VI
Hydraulic Turbines : Classification of turbines, impulse and reaction turbines, Pelton wheel, Francis
turbine and Kaplan turbine-working principles, work done, efficiencies , hydraulic design –draft tube theory-
functions and efficiency.
UNIT VII
Performance of hydraulic turbines : Geometric similarity, Unit and specific quantities, characteristic
curves, governing of turbines, selection of type of turbine, cavitations, surge tank, water hammer.
UNIT VIII
Centrifugal pumps : Classification, working, work done – manometer head- losses and efficiencies specific
speed- pumps in series and parallel-performance characteristic curves, NPSH.
Reciprocating pumps : Working, Discharge, slip, indicator diagrams.
