APPLIED HYDRAULIC ENGINEERING
To introduce the students to various hydraulic engineering problems like open channel flows
and hydraulic machines. At the completion of the course, the student should be able to
relate the theory and practice of problems in hydraulic engineering.
Definition and differences between pipe flow and open channel flow - Types of Flow - Properties of
open channel - Fundamental equations - Velocity distribution in open channel - Steady uniform
flow: Chezy equation, Manning equation - Best hydraulic sections for uniform flow Computation in Uniform Flow - Specific energy and specific force - Critical depth and velocity.
UNIT II GRADUALLY V ARIED FLOW
Dynamic equations of gradually varied and spatially varied flows - Water surface flow profile
classifications: Hydraulic Slope, Hydraulic Curve - Profile determination by Numerical method:
Direct step method and Standard step method, Graphical method - Applications.
UNIT III RAPIDLY VARIED FLOW
Application of the energy equation for RVF - Critical depth and velocity - Critical, Sub-critical and
Super-critical flow - Application of the momentum equation for RVF - Hydraulic jumps - Types Energy dissipation - Surges and surge through channel transitions.
Impact of Jet on vanes - Turbines - Classification - Reaction turbines - Francis turbine, Radial flow
turbines, draft tube and cavitation - Propeller and Kaplan turbines - Impulse turbine - Performance
of turbine - Specific speed - Runaway speed - Similarity laws.
Centrifugal pumps - Minimum speed to start the pump - NPSH - Cavitations in pumps - Operating
characteristics - Multistage pumps - Reciprocating pumps - Negative slip - Flow separation
conditions - Air vessels, indicator diagrams and its variations - Savings in work done - Rotary
pumps: Gear pump.
TOTAL (L:45+T:15): 60 PERIODS
The students will be able to apply their knowledge of fluid mechanics
in addressing problems in open channels.
They will possess the skills to solve problems in uniform, gradually and
rapidly varied flows in steady state conditions.
They will have knowledge in hydraulic machineries (pumps and turbines).
