Students studying JNTUK R20 Civil Branch, Can Download Unit wise R20 2-2 Hydraulics and Hydraulic Machinery (H&HM) Material/Notes PDFs below.

OBJECTIVES:

• Study non-uniform and uniform flows in an open channel and as well to understand the properties of hydraulic jumps
• In this article, we will introduce dimensional analysis to fluid flow issues
• To comprehend the working principles of the various Hydraulic Pumps and machines.

UNIT-1
UNIFORM FELLOWS In OPEN channel: Types of channels -Types of flow – Velocity distribution energy and momentum correction factors Chezy’s and Manning’s formulae to create uniform flow. – The most economical sections Critical flow Specific energy-critical depth Calculation of critical depth

UNIT-2
non-uniform flows in OPEN channels: Steady Gradually Varied flow dynamic equation. Mild. Critical, steep vertical and adverse slopes-surface profiles-direct steps method- Rapidly variable flow, hydraulic jumps, and energy dissipation.

UNIT-3
HYDRAULIC SIMILITUDE: Dimensional analysis-Rayleigh’s method and Buckingham’s pi theorem-study of Hydraulic models – Geometric, kinematic, and dynamic similarities-dimensionless numbers – model and prototype relations.

UNIT-4
THE BASICS OF TURBOMACHINERY: Hydrodynamic force of jets acting on stationary and moving flat, inclined, and curving vanes with a central plane as well as at the tip, speed triangles at the outlet and inlet as well as expressions for work done and efficiency-Angular principles of momentum.

UNIT-5
HYDRAULIC Turbines I The layout of a typical Hydropower installation Heads and Efficacy – the classification of turbines. Pelton wheel Francis turbine Kaplan turbine Working, working ratios and velocity diagrams working, efficiency and work and hydraulic design. Draft tube theoretical and efficient. They govern turbine-surge tanks-unit and specific quantities, selection of turbines, performance characteristics-geometric similarity-cavitation.

PUMPS:
