OBJECTIVES:

  • The applications of the conservation laws to flow through pipes and hydraulic machines are studied
  • To understand the importance of dimensional analysis.
  • To understand the importance of various types of flow in pumps and turbines.

 

UNIT I             FLUID PROPERTIES AND FLOW CHARACTERISTICS                                              8

Units and dimensions- Properties of fluids- mass density, specific weight, specific volume, specific gravity, viscosity, compressibility, vapor pressure, surface tension and capillarity. Flow characteristics

– concept of control volume - application of continuity equation, energy equation and momentum

equation.

 

UNIT II            FLOW THROUGH CIRCULAR CONDUITS                                                                   8

Hydraulic and energy gradient - Laminar flow through circular conduits and circular annuli-Boundary layer concepts – types of boundary layer thickness – Darcy Weisbach equation –friction factor- Moody diagram- commercial pipes- minor losses – Flow through pipes in series and parallel.

 

UNIT III           DIMENSIONAL ANALYSIS                                                                                           9

Need for dimensional analysis – methods of dimensional analysis – Similitude –types of similitude - Dimensionless parameters- application of dimensionless parameters – Model analysis.

 

UNIT IV          PUMPS                                                                                                                          10

Impact of jets - Euler’s equation - Theory of roto-dynamic machines – various efficiencies– velocity components at entry and exit of the rotor- velocity triangles - Centrifugal pumps– working principle - work done by the impeller - performance curves - Reciprocating pump- working principle – Rotary pumps –classification.

 

UNIT V           TURBINES                                                                                                                    10

Classification of turbines – heads and efficiencies – velocity triangles. Axial, radial and mixed flow turbines. Pelton wheel,  Francis turbine and Kaplan turbines- working principles - work done by water on the runner – draft tube. Specific speed - unit quantities – performance curves for turbines – governing of turbines.

 

 

OUTCOMES:

 

TOTAL: 45 PERIODS

 

  • Upon completion of this course, the students can able to apply mathematical knowledge to predict the properties and characteristics of a fluid.
  • Can critically analyse the performance of pumps and turbines.
