How much water is in an acumulanibus?

An acumulanibus is not a standard term in meteorology or hydrology, so it may be a typographical error or a misunderstanding of "cumulonimbus," which is a type of cloud. Cumulonimbus clouds can contain a significant amount of water, with estimates ranging from about 500,000 to 1 million liters of water in a single cloud, depending on its size and density. However, the exact amount can vary widely based on specific conditions.
