specific yield 1. The ratio of the water drained from a rock under the influence of gravity, or removed by pumping, to the total volume of the rock voids or pore space in the drained rock. The difference is caused by the retention of water in the rock, owing to molecular attraction and capillarity.See specific retention. 2.

Buoyancy. Buoyancy is the tendency of an object to float in a fluid, such as air or water. The principle of buoyancy was first discovered by Greek mathematician Archimedes (c. 287 – 212 b.c.) and is therefore often called Archimedes' Principle. Legend has it that Archimedes was working on a problem given to him by the king of ancient …
