These ratios assume 100% energy efficiency. Actual water delivered will be further reduced by the energy efficiency factor. In the above example, if the energy efficiency is 70%, the water delivered will be 70% of 20%, i.e. 14%. Assuming a 2-to-1 supply-head-to-delivery-head ratio and 70% efficiency, the delivered water would be 70% of 50%, i.e ...
A schematic presentation of a gravitation water vortex power plant, showing the turbine in yellow. The gravitation water vortex power plant is a type of micro hydro vortex turbine system which converts energy in a moving fluid to rotational energy using a low hydraulic head of 0.7–3 metres (2 ft 4 in – 9 ft 10 in).
A pump as turbine (PAT), also known as a pump in reverse, is an unconventional type of reaction water turbine, which behaves in a similar manner to that of a Francis turbine. The function of a PAT is comparable to that of any turbine , to convert kinetic and pressure energy of the fluid into mechanical energy of the runner.
An energy tower (also known as a downdraft energy tower, because the air flows down the tower) is a tall (1,000 meters) and wide (400 meters) hollow cylinder with a water spray system at the top. Pumps lift the water to the top of the tower and then spray the water inside the tower. Evaporation of water cools the hot, dry air hovering at the top.
Due to the rotation, water is then picked up by the tube and pumped upwards in the hose. The coil pump, as many low lift pumps, is commonly used for irrigation purposes and for drainage of lands. It is currently still used by farmers in Asia. [1] The coil pump was built as an alternative to the Archimedean screw. Unlike the Archimedean screw ...
State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
