DESCRIPTION OF COURSES
WST 501 FUNDAMENTALS OF FLUID MECHANICS AND HYDRAULICS (3L+1P) I
To impart the basic knowledge of the fluid mechanics and hydraulics to the students of various background. Such a basic knowledge is a mandatory requirement for those who deal with water transport on to the fields.
Fluids- definitions, properties, fluid pressure and its measurements, hydrostatic force on surface, buoyancy and floatation.
Hydro kinematics- kinematics of fluid flow, methods of describing fluid in motion, lines of flow: path line, stream line, stream tube and potential line.
General types of fluid flow- steady and unsteady flow, uniform and non uniform flows, laminar and turbulent flows, compressible and incompressible flows, one, two and three dimensional flows.
Rate of flow/discharge, system, control volume, cross section of flow, concept of mean velocity of flow, Equation of continuity, Stream function, velocity function and flow net.
Dynamics of fluid flow, basic energy and momentum equation, Bernoulli’s theorem for liquid and its proof, Hydraulic and energy grade lines, head and power: horse power, application of Bernoulli’s equation.
Flow through pipes, definition of pipe and pipeline, pipe line problems, siphon, loss of head in pipe, pump in pipe line, most economical diameter of pipe, water hammer, gradual closure of valve, and instantaneous closure of valve.
Design problems, Exposure to various hydraulic structures, solutions to class exercises and design exercises of pipe flows.
