problem:- A circular tank of diameter 4m contains water up to a height to 5m. Orifice of diameter 0.5m at the bottom. Find the time taken by water:- 1. To fall from 5m to 2m 2. For completely emptying to tank take cd=0.6

What is OMC (optimum moisture content) and MDD (maximum dry density).

· What is OMC (optimum moisture content) and MDD (maximum dry density). The moisture content goes on increasing till its maximum value of dry density is called maximum dry density (MDD). The moisture content corresponding to the maximum dry density is called optimum moisture content (OMC).
