### Anna University Regulation 2013 Electrical & Electronic Engineering (MECH) 3rd SEM CE6451 FMM -Fluid Mechanics Machinery Syllabus

#### 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.
TOTAL: 45 PERIODS

OUTCOMES:

• 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.TEXT BOOK:
