What force allows this huge iceberg to float instead of sinking to the botton of the ocean

The Bouyant force

Explanation:

The reason there's a buoyant force is because of the rather unavoidable fact that the bottom of an object is always deeper in a fluid than the top of the object. This means the upward force from water has to be greater than the downward force from water.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
