Pico Hydro Turbines: Pico hydro turbines are small-scale turbines designed for low-flow water sources. These turbines are specifically tailored for off-grid power supply in remote areas. By optimizing the design and efficiency of these turbines, it becomes possible to generate electricity in even the most challenging environments .
The power in a flow. The relevant calculation for the power contained in a flow through a rotor is: Power (in watts) = ( V^3 ) x 0.5 x p x A. V is the water flow speed in metres per second – this then needs to be cubed (raised to the power of 3). p is the density, which is about 1000 kg per cubic metre for water.
The Jack Rit turbine is designed for low-flow scenarios and can generate power from streams with as little as 13 inches of water and no head. Although its output is limited to a maximum of 100 Watts, it can still provide a daily average of 1.5 to 2.4 kilowatt-hours, depending on the site.

Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial Revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time.

Most reaction water turbines are used with low or medium heads but with a larger volume of water. Turbines can also subclassified as radial design or axial design . In a radial-flow turbine, the flow enters in the direction the turbine moves and exits along the axis of
Working on the development of very low head (VLH) turbines from day one, the director of the Canadian company Novatech-Lowatt Turbines, Claude O''Neil, will talk about a new generation of small hydro projects at the event. Ahead of the conference, he gives an insight into some of the recent research achievements of VLH turbines.
This chapter provides an overview of hydraulic turbines. Water turbine is a device that transforms the potential energy of a head of water into mechanical work. Turbines vary widely in form and application. At one extreme is the pure impulse machine where the flow is generally low but the head is large.

For convenience in terminology, this scale of hydropower is referred to as micro-hydro. Micro-hydro systems generally consist of the following components: A trash rack, weir, and forebay to prevent debris from entering the pipeline and turbine. A pipeline (also called a penstock) to pipe water to the turbine.
According to Fig. 1 [15], Kaplan turbine looks like a promising turbine for the water pipeline because it can work at low flow rate and low water head condition.But Kaplan turbine will alter the pathway of water flow and cannot be well integrated with pipeline. Ampair''s
In the last few decades, hydropower production has been moving toward a new paradigm of low and diffused power density production of energy with small and mini-hydro plants, which usually do not require significant water storage. In the case of nominal power lower than 20 kW and ultra-low head H (H < 5 m), Archimedes screw or Kaplan
When water flows through the turbine, it exerts pressure on the turbine blades, causing them to rotate. This rotational motion is then transferred to a generator, which converts the mechanical energy into electrical energy.The amount of power generated depends on factors such as the flow rate of water and the efficiency of the turbine.
A crossflow turbine is designed using a large cylindrical mechanism composed of a central rotor surrounded by a "cage" of blades arranged into a water wheel shape. These blades are generally sharpened to increase
A Pelton turbine, also known as a Pelton wheel turbine, is an impulse turbine uniquely designed to convert the kinetic energy of water into mechanical energy. Unlike its counterparts – the Francis and Kaplan turbines, which are reaction turbines suited for lower-head and higher-flow applications – the Pelton turbine operates

Turbines suitable for use in very-low-head applications are different from the Francis, propeller, Kaplan, or Pelton types used in more conventional large hydro. Different types of low-head turbines are: • Venturi-enhanced turbine: This type of turbine uses venturi principles to achieve a pressure amplification for the turbine so that smaller, faster, no-gearbox turbines can be deployed in low-
Many sites will not always have a sufficient streamflow to both provide water to the turbine and maintain a low environmental impact. Therefore, the volume of water diverted to the turbine must be managed.
Kinetic energy turbines, also called free-flow turbines, generate electricity from the kinetic energy present in flowing water rather than the potential energy from the head.

The Kaplan turbine is a specialized water turbine designed to generate electricity from flowing water, especially in low-head, high-flow environments. Introduced in 1913 by its namesake, Viktor Kaplan, this turbine has since carved a niche for itself in the world of renewable energy [1]. At its core, the Kaplan turbine working principle
