Correctly to look after the pool – to correct acidity level, to add disinfectants or to oxidize water – very important to know its volume since it is desirable to apply all these substances in certain dosage. To calculate the sizes necessary for you easily on several mathematical formulas.
Instruction
1. The best way which allows to calculate most precisely the volume of the pool is measurement of water flow during filling of the pool. For this purpose it is necessary to connect only to system by means of which you pump water in your artificial reservoir, the device hydrometer and to look at its indications. On the counter you will see water volume in cubic meters. If it is impossible to use this method for some reason, use knowledge of mathematics.
2. If your pool has accurate rectangular shape, measure its length and width (in meters) and multiply these digits. You receive the area of the pool. Then measure height (depth) on which you fill the pool with water, and increase it by the square. Pool volume in cubic meters will also be result.
3. If length, width and depth of the pool in different points are various, to perform exact measurements of volume much more difficult. You can arrive thus. Measure by means of tape measure each side of the pool and its depth in various places. Then take the sheet of paper in cage and in certain scale draw the image of the pool. For example, one cage is one meter. For determination of the area rather just to count quantity of cages. And if the cage is outlined more than half, consider it for unit and if less, than half, then for zero. The pool projection on depth can be executed on paper too and to calculate as well as the area – on the occupied cages.
4. In case the pool reminds difficult geometrical figure, it can also be broken mentally into several simpler figures and to calculate volume separately for each of them, and then to put all results together. In mathematics there are formulas for determination of the area of triangle, trapeze, parallelogram, rhombus and other figures, and you can easily use that which will approach form of your reservoir more.
5. If your pool round, in fact, you need to calculate cylinder capacity. This work of the area of dock apron on height which is occupied by water. The area of bottom is defined as the work of constant of Pi (3.14) on radius in square. Further increase result by depth of the pool and receive the volume necessary to you.
6. To find the volume of the pool, oval in form, you too at first need to calculate the area of bottom. It is determined by formula S=3.14xAxB where And is the length of big half shaft, and In – length of minor half shaft. Having increased the received work by depth, you receive required volume.
