They decided that the system should be based on the follow conditions: In 1790 the French Academy of Science got an instruction of the National Assembly to design a new standard of units for the whole world. It is the standard metric system nowadays. SI is the abbreviation for Système International d'Unités. More information in The United States and The Metric System. This was decided in the Omnibus Trade and Competitiveness Act Of 1988. The United States converted to the international standard metric system under pressure of the industry in 1988. The United States had their own metric system for a very long time. More information in The Weights and Measures Act 1985 (Metrication) (Amendment) Order 1994. In 1985 the English changed officially to the standard metric systems. Just like in the SI, the units were multiplied by each other. These consisted on feet, yards, inches, miles etc for length. Because the unit of length is the meter, and volume is m Įngland had its own metric system for a very long time. If you don't, the calculations will be wrong. So, if you want the volume in cubic meters, you will have to fill in all the data in meters. You will have to be consequent with the units. These are pyramid, truncated pyramid, cylinder, hollow cylinder (pipe), cone, truncated cone, sphere, the segment of a sphere and a barrel. Here are some geometrical bodies, whose volume can be calculated. Separation and Concentration Purification RequestĬonvert the units from the American metric system to the British metric system and the standard metric system (SI).Plant Inspection & Process Optimalisation.An acre-inch, the volume of water needed to cover an acre to a depth of 1 inch, 1/12th of an acre-foot, is approximately 27,154.25 gallons or approximately 102.79 cubic meters.Įnter the surface percentage of the cylinderįormula - TV = VT1 + VT2 + VT3 + VT4 + VR +VCīelow are area and acre calculations. At year 2000 considering American rates of consumption, on average 1 acre-foot of water is enough to meet the industrial and municipal demands of 4 people for a year. gallons (approximately 1233.48 cubic meters). One acre-foot is the volume of water sufficient to cover an acre of land to a depth of 1 foot, is equal to 43,560 cubic feet, approximately 325,851 U.S. Both are units used to measure volumes of water, typically for use in irrigation. In the second calculator, assuming that your entry values were in feet, the number of surface acres is returned, along with the number of acre-feet and acre-inches of water volume, based on the entered depth. The answers are returned as cubic unit numbers, based on your entries. The depth is from the surface of the structure to the flooring and is consistent in all calculations if this is not a universal depth, take an average. Any combination can be used and the potential of the shapes possible is almost limitless.
In triangles, the height is measured in a perpendicular from the highest point to the base. If you only have one triangle and a rectangle, only use those fields. Enter the height and base of all of the triangles in each Triangle section required (up to 4), and length and width dimensions in the Rectangle section. Enter the consistent or average depth used in all the calculations. If it is a full circle, leave the default of 100 percent.) They do NOT need to be right triangles. (As an example, if the circular surface is a semi-circle, put in 50 as the percentage. If it is a cylinder, enter the radius or 1/2 of the diameter also enter the percentage of the cylinder used. If it is an irregular reservoir, segment it into the surface shape of a rectangle and up to four triangles. If it is a square or rectangle surface shape, enter the depth, length and width dimensions in the Rectangle section only. In this calculator, the reservoir is assumed to be irregular but it could be the surface shape of a square, a rectangle, a circle (or percentage thereof), a triangle, all with depth (examples might be a cube, cylinder, rectangular prism or triangular prism, or an irregular shaped of those combinations), volume capable, structure. There are basic environmental concerns as possibilities, however, this calculator's purpose is to provide an approximate volume as needed. This calculator does not approach the construction methods of the reservoir, only the volume requirements. For the purposes of this calculator, a reservoir is a structure, pool, tank, basin, container, pond or lake, of regular or irregular shape, to hold water, for a specific purpose. It is to determine the volume of a reservoir structure the reservoir can actually contain water or potentially contain water, depending on the purpose.
