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 tube, 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 don 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 proportions, work done, efficiencies , hydraulic design –draft tubetheory-
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, cavitation, surge tank, water hammer.
UNIT-VIII
Centrifugal pumps: classification, working, work done – manomertic head- losses and efficienciesspecific
speed- pumps in series and parallel-performance characteristic curves, NPSH.
Reciprocating pumps: Working, Discharge, slip, indicator diagrams
