Vertical Cylindrical Storage Tank


This type of tank is more easily to calculate the total volume of liquid contained in it, if compared with a horizontal cylindrical tank which is more complicated. Simply by calculating the area of ​​the base of cylinder and then multiplied by the height or depth of the liquid, then it will be directly obtained fluid volume inside the tank.

Fluid Volume = area of ​​base x height of fluid = 22 / 7 x radius x radius x height of fluid

Use the measurements on the inside of the tank for better accuracy.

For large tank sizes, usually vertical cylindrical tanks are popularly used. But it needs not be considered to design a vertical tank that is not too high, or so-called low profile design, to make it more safety. One of the reason is because it will be easier for a lightning strike if it is too high. Low profile tank is easy to climb for maintenance and check.

For tanks that can store 100,000 liters or more, expansion and shrinkage of fluid due to ambient temperature is very noticeable. Temperatur changes from night to day, which is about 10 degrees Celcius or 18 degrees Fahrenheit, and vice versa from day to night, can be clearly seen at the height of liquid level in the tank. Therefore the tank should not be built too high to avoid confusing as ambient temperature change.

Some tanks are designed with a roof that can be moved up and down to follow the height of the liquid. This aims to avoid the buildup of vapor above the liquid, usually applied to liquids with flammable vapors.
