The knowledge of fluid flow is very essential because all chemical plants have transportation of fluids. The examples may be flow of steam and gases in pipes, flow of liquid in pipes and open channels etc. The course will aim at the basic concepts of fluid flow, measurement techniques involved for the same and equipments used for the transportation of fluids. With this background, students will be able to quantitatively find out material and power requirements for a process.
1. Introduction (8 hrs)
Fluid, types of fluid i.e. real fluid and ideal fluid, compressible fluid and incompressible fluid, properties of fluid i.e. viscosity, surface tension, compressibility, density, specific gravity etc., path line, stream line, stream tube and potential lines, steady flow, unsteady flow, uniform flow, non-uniform flow, laminar and turbulent flow, rotational and irrotational flow.
2. Flow of Incompressible Fluids (14 hrs)
Classification into Newtonian and Non Newtonian fluids. Flow in boundary layer, continuity equation, Bernoulli’s equation, friction factor, skin frictions, form frictions, Reynolds’s number, fanning friction equation, friction losses from sudden expansion and sudden contraction of cross section, effect of fitting, valves and roughness.
3. Transportation of Fluids (18 hrs)
Classification of pumps, use of different types of pumps like reciprocating, rotary, and gear pumps. Working and construction of centrifugal pump. Priming. Cavitation and NPSH. Characteristics curves of centrifugal pump. Introduction of Fans, Blowers and Compressors. Valves: types and applications of valves i.e. Gate valve, Globe valve, Ball valve, Plug valve, Butterfly valve and Diaphragm valve.
4. Measurement of Flow of Fluids (8 hrs)
Types of measurement i.e. volumetric flow rate and mass flow rate. Construction and working principle of pitot tube, orificemeter, V-notch, venturimeter and rota-meter.
