Gift in kind; shown at the left is the CIE 1931 Chromaticity Diagram.
He applied scientific principles and testing methods to the problem of turbine design. His mathematical and graphical calculation methods allowed confident design of high efficiency turbines to exactly match a site’s specific flow conditions. The power source was normally a head of water, which could also be assisted by a pump. In these designs, a falling column of water is purposely mixed with air bubbles generated through turbulence or a venturi pressure reducer at the high level intake. This is allowed to fall down a shaft into a subterranean, high-roofed chamber where the now-compressed air separates from the water and becomes trapped.
The height of the falling water column maintains compression of the air in the top of the chamber, while an outlet, submerged below the water level in the chamber allows water to flow back to the surface at a lower level than the intake. A separate outlet in the roof of the chamber supplies the compressed air. 1910 and supplied 5,000 horsepower to nearby mines. 10 megawatts or less and often have no artificial reservoirs. 60 seconds of the need arising. Pressure buffering hydropower is the compilation of run-of-river and pumped storage hydro power generation. The static head is proportional to the difference in height through which the water falls.
Dynamic head is related to the velocity of moving water. Each unit of water can do an amount of work equal to its weight times the head. The power available from falling water can be calculated from the flow rate and density of water, the height of fall, and the local acceleration due to gravity. In English units, the density is given in pounds per cubic foot so acceleration due to gravity is inherent in the unit of weight. Operators of hydroelectric stations will compare the total electrical energy produced with the theoretical potential energy of the water passing through the turbine to calculate efficiency. Field testing of turbines is used to validate the manufacturer’s guaranteed efficiency. Detailed calculation of the efficiency of a hydropower turbine will account for the head lost due to flow friction in the power canal or penstock, rise in tail water level due to flow, the location of the station and effect of varying gravity, the temperature and barometric pressure of the air, the density of the water at ambient temperature, and the altitudes above sea level of the forebay and tailbay.
Over-shot water wheels can efficiently capture both types of energy. The water flow in a stream can vary widely from season to season. Dams and reservoirs provide a more dependable source of power by smoothing seasonal changes in water flow. As with other forms of economic activity, hydropower projects can have both a positive and a negative environmental and social impact, because the construction of a dam and power plant, along with the impounding of a reservoir, creates certain social and physical changes. This provides a base-line understanding of the pre-project conditions, estimates of potential impacts and puts in place management plans to avoid, mitigate, or compensate for impacts. It is a methodology used to audit the performance of a hydropower project across more than twenty environmental, social, technical and economic topics.
