Sizing tanks and dikes

Development of optimum sizes for tanks and dikes comes through trial and error. Considerations include the availabiliw of real estate, the po.ssible use of standard-sized tanks for. smaller capacities, and the nature of potential foundation design problems caused by early tank-size seleaions. The de.signer should refer to API 12F for standardized shop-fabricated tank sizes. Larger field-fabricated storage tanks must be sized to suit each site. 

AS an example of how to develop tank height and dike. size, a 150,000-barrel (42 galloas per barrel). 150-foot-diameter tank is used. The first step is to convert the tank volume into cubic feet, as follows  

Tank height i.s calculated according to the foliow ing equation  

R bottom of berm radius (79.5 ft) h berm height (1 foot) 

Dikes containing multiple tanks are sized to hold the capacity of the largest tank. For the dimensions of dikes containing more than one tank, it is necessary not only to subtract the volume of each tank from the dike s capacity but to subtract the volume of the soil in each berm.
