  2. Rajanganaya Dam - Wikipedia

    en.wikipedia.org/wiki/Rajanganaya_Dam

    The Rajanganaya Dam (sometimes called Rajangana) is an irrigation dam built across the Kala Oya river, at Rajanganaya, bordering the North Western and North Central provinces of Sri Lanka. The main concrete dam measures approximately 350 m (1,150 ft) and creates the Rajanganaya Reservoir, which has a catchment area of 76,863.60 hectares ...

  3. Hydrostatic loop - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_loop

    A hydrostatic loop, though not often used in plumbing practice, is an arrangement of pipes formed into a vertical loop to prevent backflow of water within the plumbing potable water system. Since a siphon has a maximum height that it can work (about 33 feet), a hydrostatic loop is built higher than 33 feet. There are several ways to prevent ...

  4. Hydrodynamic stability - Wikipedia

    en.wikipedia.org/wiki/Hydrodynamic_stability

    Bifurcation theory is a useful way to study the stability of a given flow, with the changes that occur in the structure of a given system. Hydrodynamic stability is a series of differential equations and their solutions. A bifurcation occurs when a small change in the parameters of the system causes a qualitative change in its behavior,. [1]

  5. Control loop - Wikipedia

    en.wikipedia.org/wiki/Control_loop

    A control loop is the fundamental building block of control systems in general and industrial control systems in particular. It consists of the process sensor, the controller function, and the final control element (FCE) which controls the process necessary to automatically adjust the value of a measured process variable (PV) to equal the value of a desired set-point (SP).

  7. Tank cascade system - Wikipedia

    en.wikipedia.org/wiki/Tank_cascade_system

    The tank cascade system (Sinhala: එල්ලංගාව, romanized: ellaṅgāva) is an ancient irrigation system spanning the island of Sri Lanka. It is a network of thousands of small irrigation tanks ( Sinhala : වැව , romanized: wewa ) draining to large reservoirs that store rainwater and surface runoff for later use.

  8. Root locus analysis - Wikipedia

    en.wikipedia.org/wiki/Root_locus_analysis

    According to vector mathematics, the angle of the result of the rational polynomial is the sum of all the angles in the numerator minus the sum of all the angles in the denominator. So to test whether a point in the s-plane is on the root locus, only the angles to all the open loop poles and zeros need be considered. This is known as the angle ...

  9. Uma Oya Hydropower Complex - Wikipedia

    en.wikipedia.org/wiki/Uma_Oya_Hydropower_Complex

    The Uma Oya Hydropower Complex (also internally called Uma Oya Multipurpose Development Project or UOMDP) is an irrigation and hydroelectric complex in the Badulla District of Sri Lanka. Early assessments of the project date back to 1989, when the first studies was conducted by the country's Central Engineering and Consultancy Bureau.
