We have determined the serum content of vitamin B12 by microbiologic assay in patients with acute and chronic liver disease and have investigated the absorption, the urinary excretion and the plasma clearance of radioactive vitamin B12.
The amount of gallons of water in a pool varies greatly depending on the size of the pool. The average in-ground backyard pool holds between 18,000 and 20,000 gallons of water.
Why do you need to know you Pool's Water Volume? In order to figure out proper doses of chemicals for your pool, you need to accurately determine how many gallons of water it holds. To do that, you need to know four different numbers: the length, width, average depth, and a multiplier for your type of pool. Length x Width x Average Depth x Multiplier = Volume in US Gallons. Multiplier = 7.5 for Rectangle, Square, or Free-Form pools.
