UNIT I UNIFORM FLOW
Definition and differences between pipe flow and open channel flow — Types of Flow — Properties of open channel — Velocity distribution in open channel — Steady uniform flow: Chezy equation, Manning equation — Best hydraulic sections for uniform flow — Wide open channel — Specific energy and specific force — Critical flow .
UNIT II GRADUALLY VARIED FLOW
Dynamic equations of gradually varied flows — Types of flow profiles — Classifications: Computation by Direct step method and Standard step method — Control section — Break in Grade — Computation.
UNIT III RAPIDLY VARIED FLOW
Application of the momentum equation for RVF — Hydraulic jumps — Types — Energy dissipation — Celerity — Rapidly varied unsteady flows (positive and negative surges)
UNIT IV TURBINES
Impact of Jet on flat, curved plates, Stationary and Moving –Classification of Turbines — Pelton wheel — Francis turbine — Kaplan turbine — Specific speed — Characteristic Curves of Turbines- Draft tube and cavitation.
UNIT V PUMPS
Classification of Pumps — Centrifugal pumps — Work done — Minimum speed to start the pump — NPSH — Multistage pumps — Characteristics curve — Reciprocating pumps — Negative slip — Indicator diagrams and its variations — Air vessels — Savings in work done.
