The Euler pump and turbine equations are the most fundamental equations in the field of turbomachinery.These equations govern the power, efficiencies and other factors that contribute to the design of turbomachines.
[10] Dartmouth Dam: Victoria Australia: The 180MW Francis turbine-generator running at full speed was instantaneously stopped by a foreign body left in the penstock following maintenance.[7] The installation shifted about 2m within the base of the 180m high earth and rock fill gravity dam wall of the 3,906GL reservoir.

The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field.
Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2]
The Archimedean screw turbine is applied on rivers with a relatively low head (from 0.1 m to 10 m) and on low flows (0.01 m 3 /s up to around 10 m 3 /s on one turbine). Due to the construction and slow movement of the blades of the turbine, the turbine is considered to be friendly to aquatic wildlife.
In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid is the kinetic energy associated with the speed of flow of the fluid, plus energy from static pressure in the fluid, plus energy from the height of the fluid relative to an ...
