Pico-Hydro Power
Investigations into application of two prime mover variants for Pico-Hydro Generation
Abstract- This paper presents simple design procedure of a turbine and water wheel for use in Pico hydro generating units. Authors have designed and fabricated a turbine and water wheel and tested them at two different sites for electrical power generation. A scheme is suggested to obtain desired a. c. voltage and frequency to enable the unit to be used for domestic appliances. Test results are presented. Applications of such units are discussed. Key words- Pico-hydro generation; water wheel; turbine; induction generator; embankment;

WATER TURBINES Turbines are either impulse or reaction type. In impulse turbines, water jet strikes the buckets of the turbine and imparts its energy to the turbine. In reaction turbines water imparts its energy to the blades while moving through them. The blades in reaction turbine are always immersed in water. Bilal A. N. (2013), presented MATLAB design of a small hydro power station [2]. P. Adhikari et al (2013) presented design of propeller turbine for Pico hydro generation [3]. Bilal A. N. (2013), presented a design of Pelton turbine [4]. For head above 10 meters impulse type turbines are used. They are simple in construction and can be easily fabricated. These turbines are suitable for Pico hydro generation [5]. Fig. 1 shows half section of a turbine. Fig. 1 Half section of a turbine The blades are of cup shape and water strikes at the center of the cup through a nozzle. Fig. 2 shows one blade or cup of the …show more content…
The motor can generate electrical power when excitation capacitors of sufficient value are connected across its windings. This assembly was tested at the location mentioned above. At the time of testing, three capacitors of 20 µf each were connected in delta across the generator terminals. Load test readings when three capacitors of 13.66 µf were connected across generator terminals, are shown in table - 1. Load test readings when three capacitors of 17.5 µf were connected across generator terminals, are shown in table - 2. Fig. 5 shows variation in terminal voltage and speed with output

430 Words | 2 Pages4.11 Motor A DC motor is an electrical machine which converts electrical energy into mechanical energy. A magnetic field is generated by the current carrying conductor and when this system is placed in external magnetic field then the force is exerted which is proportional to the strength of the external magnetic field and to the current in the conductor, then motor will rotate. If the direction of current is reversed then the direction of rotation of motor will also reverse.

821 Words | 4 PagesThe turbines have to be a certain number of feet in the air. Are there trees, buildings and other obstacles that would block the wind? Is there a fast flowing waterway in which you would have rights and access to so you can install hydro generators if needed? Fourth Concern: Natural Disasters Is the property in a flood zone? Zones change all the time, and even if not in a so-called flood zone is there a chance the property could be flooded.
Eli Whitney And The Cotton Gin
1925 Words | 8 PagesThe machine was powered by a hand crank that turned two cylinders with teeth on it. One cylinder would separate the seeds from the cotton and the other cylinder would pull the cotton into a separate compartment (Whitney, 2014). It was important to separate the seeds into a different compartment because they also had economic value, but nowhere in comparison to that of cotton. The seeds were used in cottonseed oil that was used in the production of candy, cooking, cattle feed and paper (Woods, 2009).

Persuasive Essay Against Nuclear Energy
620 Words | 3 PagesNuclear energy has long been proposed as a viable alternative to fossil fuels for energy worldwide since the first commercial nuclear power stations began operation in the United States during the 1950s. At present, there are over 435 commercial nuclear power plants operating in 31 countries worldwide, generating 11 percent of the world’s power. Nuclear plants are able to generate large amounts of energy through the splitting of atomic nuclei in a process known as nuclear fission. The amount of energy released by nuclear fission is measured in units of electron volts, eV, and typical figures can range up to 200 million electron volts. Compared to the combustion of fossil fuels, which release only a few electron volts per reaction, nuclear power dominates in terms of power

Essay On Wind Energy
1104 Words | 5 PagesWhat happens is that since the air on the land takes less time to heat up than the air on the ocean, the warm air on the land starts to rise and expand. As the warm air rises the cold air flows into its place as, hence creating a flow of air, which is wind. During the night the opposite happens. The air on the land cools down faster than the air on the water, the same process occurs and wind is again created, meaning that a wind turbine can be used day and night. The only necessary condition for wind turbines to work is that there is wind, which turns the blades.
Research Paper On Wind Energy
808 Words | 4 PagesWind energy, the energy harvested from wind, by means of a mechanical generator through the torque applied, is very Earth friendly. There are multiple ways of generating energy from wind, the most common being the white three-bladed design, known as the horizontal axis wind turbine. There also are the vertical axis turbines and ducted wind turbines. The different and unique designs have advantages and disadvantages; vertical axis turbines, are difficult to maintain and constructing them requires skilled operators. On the other hand vertical axis turbines, are very easy to construct and are able to operate at lower speeds.
