MSBTE K Scheme – 313309 Fluid Mechanics and Machinery
MSBTE K Scheme – Fluid
Mechanics and Machinery Notes PDF
Fluid mechanics
is one of the core subjects in engineering, especially in civil,
mechanical, and allied branches. It deals with the study of fluids
(liquids and gases), their properties, behavior, and applications in
engineering systems. When this knowledge is extended to design and analyze
machines that use fluids for performing work, it is known as Fluid Machinery.
Under the MSBTE
K Scheme, the subject Fluid Mechanics and Machinery is introduced to
provide diploma students with a strong theoretical foundation and practical
skills for solving real-world engineering problems such as water supply
systems, turbines, pumps, and hydraulic machines.
Importance of Fluid Mechanics and Machinery
- Forms the basis for hydraulic engineering, power
generation, and machine design.
- Essential for designing dams, canals, pipelines,
pumps, turbines, and irrigation systems.
- Helps in understanding fluid flow behavior
under pressure, velocity, and resistance.
- Provides knowledge to operate hydraulic machines
efficiently and safely.
- Plays a vital role in industries like power
plants, automobile, aerospace, water resource engineering, and HVAC
systems.
MSBTE K Scheme – Syllabus Overview of Fluid Mechanics
and Machinery
The syllabus is designed to give
students both analytical skills and practical exposure through
lab experiments and field applications.
Unit 1: Properties of Fluids
- Definition of fluid, difference between solids,
liquids, and gases.
- Properties of fluids: density, viscosity,
compressibility, surface tension, capillarity.
- Pressure measurement: Pascal’s law, manometers,
piezometer.
Unit 2: Fluid Statics
- Hydrostatic pressure and force on surfaces.
- Centre of pressure and applications in gates and
dams.
- Buoyancy and flotation – stability of floating
bodies.
Unit 3: Fluid Kinematics
- Types of fluid flow: laminar, turbulent, steady,
unsteady, uniform, non-uniform.
- Continuity equation and velocity potential.
- Streamlines and flow nets.
Unit 4: Fluid Dynamics
- Euler’s equation and Bernoulli’s theorem with
practical applications.
- Flow through orifices, notches, and weirs.
- Venturimeter and Pitot tube.
Unit 5: Flow through Pipes
- Loss of head due to friction (Darcy–Weisbach
equation).
- Minor losses – bends, valves, sudden
enlargement/contraction.
- Hydraulic gradient line (HGL) and energy line
(TEL).
Unit 6: Hydraulic Machines – Pumps
- Introduction to hydraulic machines.
- Centrifugal pumps – construction, working,
performance characteristics.
- Reciprocating pumps – principle, working, and uses.
- Cavitation and priming.
Unit 7: Hydraulic Machines – Turbines
- Classification of turbines – impulse and reaction.
- Pelton wheel turbine – construction and working.
- Francis turbine and Kaplan turbine.
- Draft tube and efficiency of turbines.
Practical Applications of Fluid Mechanics and
Machinery
- Civil Engineering – designing dams, canals,
pipelines, water supply networks.
- Mechanical Engineering – automobile
lubrication, aerodynamics, turbines, compressors.
- Power Sector – hydroelectric power plants
use turbines for electricity generation.
- Agriculture – irrigation pumps and water
lifting devices.
- Aerospace – design of aircraft wings and jet
propulsion systems.
Why This Subject is Important for MSBTE Students
- Builds a strong technical foundation for
higher studies and professional careers.
- Helps in competitive exams and interviews
where fluid mechanics is a key subject.
- Provides lab-based learning through
experiments on pumps, turbines, and flow measurement devices.
- Equips students with skills for jobs in construction
firms, irrigation departments, power plants, and mechanical industries.
- Connects theory with practical applications
in daily life (water supply, transportation, energy).
Real-Life Applications in India
- Bhakra Nangal Dam – water turbines generate
hydroelectric power.
- Koyna Hydroelectric Project (Maharashtra) –
Kaplan and Francis turbines used for electricity generation.
- Sardar Sarovar Project (Gujarat) – fluid
mechanics principles applied for water distribution and irrigation.
- Pune Water Supply System – pumping stations
designed using centrifugal pumps.
Study Tips for MSBTE Diploma Students
- Revise fluid properties and units thoroughly
(these are basics for advanced topics).
- Practice derivations of Bernoulli’s equation and
continuity equation with applications.
- Draw neat diagrams for turbines, pumps, and
measuring devices (important for exams).
- Solve numerical problems on head losses,
velocity, and efficiency to strengthen concepts.
- Perform lab experiments carefully (like
Venturimeter and Pelton wheel tests) to connect theory with practice.
