OBJECTIVES:

To impart to the student knowledge on
 Fluid properties, fluid statics, dynamic characteristics for through pipes and porous medium.
 Flow measurement and fluid machineries.

UNIT I PROPERTIES OF FLUIDS AND CONCEPT OF PRESSURE

Introduction – Physical properties of fluids – Types of fluids – Fluid statics and its applications – Hydrostatic equilibrium – Pressure measurement – Rheological properties of fluids.

UNIT II MOMEMTUM BALANCE AND ITS APPLICATIONS

Basic equation of fluid flow –Mass balance in a flowing fluid; continuity- Differential momentum balance; Equations of motion – macroscopic momentum balances -Bernoulli’s equation – Correction for fluid friction – Correction for pump work – Velocity potential – Reynolds experiment and significance.

UNIT III DIMENSIONAL ANALYSIS

The principle of dimensional homogeneity – dimensional analysis, Rayleigh method and the Pi theorem – non-dimensional action of the basic equations – similitude – relationship between dimensional analysis and similitude.

UNIT IV FLOW OF INCOMPRESSIBLE FLUIDS THROUGH DUCTS

Flow of incompressible fluids in pipes – Shear stress and skin friction in pipes -laminar flow in pipes and channels –Velocity profile and friction factor for smooth and rough pipes – Loss due to friction in pipes and Fittings – Fluidization – Mechanism – Types – General properties – Applications. Flow past immersed bodies, Drag and Drag coefficient, Flow through beds of solids – Ergun’s Equation.

UNIT V TRANSPORTATION AND METERING

Measurement of fluid flow – Orifice meter – Venturimeter – Rotameter – Weirs and notches – Transportation of fluids – Positive displacement pumps – Rotary and Reciprocating pumps – Centrifugal pumps – Performance and characteristics.

TOTAL: 45 PERIODS

OUTCOMES:

CO1: Understand the fundamental properties of fluids, stress-strain relationship in fluids, and its characteristics under static conditions and establish force balance in static systems.
CO2: Apply Bernouli principle, Navier – Stokes equation and compute pressure variation in static fluid.
CO3: Use of dimensional analysis to derive relationships among process or system variables. Further they would develop dimensionless roups that help in scale-up studies.
CO4: Understand the different types of flow conditions in fixed bed and fluidized beds.
CO5: Describe function of flow metering devices, apply Bernoulli equation to determine the performance of flow-metering devices and also analyze the performance aspects of fluid machinery such as pumps.
CO6: Understand the impact of technology change and also develop responsibilities to the professional engineering practices.
