CH 2203 - FLUID MECHANICS |
UNIT I INTRODUCTION |
Nature of fluids - laws of dimensional homogeneity – Physical properties of fluids –
Types of fluids-Newtonian and Non Newtonian fluids- viscosity and other secondary
properties – Compressible and incompressible fluids-hydrostatic pressure distributionslaws
of buoyancy Pressure measurements manometers. |
UNIT II KINEMATICS OF FLUID FLOW |
Velocity potential, concept of boundary layer, form drag, skin drag-Drag coefficient-
Continuity, momentum and mechanical energy equations; Laminar and turbulent flow
through closed conduits, velocity profiles and friction factor for smooth and rough pipes. |
UNIT IIIDIMENSIONAL ANALYSIS AND MEASUREMENT OF FLUID FLOW |
The principle of dimensional homogeneity - the Pi-theorem - relationship between
dimensional analysis and similitude - use of dimensional analysis for scale up studies-
Orifice meter, Venturimeter, Pitot tube, Rota meter, Weirs and notches- Principles and
applications of Doppler effect in flow measurement. |
UNIT IVVISCOUS FLOW IN DUCTS AND BOUNDARY LAYER FLOW |
Reynolds’s number regimes, internal versus external viscous flow, flow in circular pipe -
head loss, minor losses in pipe systems and multiple-pipe systems - functions and
pressure drag - flow through packed and fluidized beds. |
UNIT VFLOW MEASUREMENT AND TUBRO MACHINERY |
Fluid moving machinery performance - selection and specification; Air lift and diaphragm
pump – positive displacement pump – reciprocating and rotary pumps – centrifugal
pump; pump characteristics. Fans, blowers and compressors – steam jet ejector. |
