n: a three- or four-wire connection, resembling the letter Y, used in three-phase circuits alone or in various combinations with delta connections.

n: a biopolymer produced from a particular strain of bacteria on carbohydrates that produces large increases in apparent viscosity while maintaining fairly good control of filtration.

n: on a mobile offshore drilling rig or ship, the angular motion as the bow or stern moves from side to side. v: to move from side to side (as a ship).

n: see hydraulic control pod. yield n: the number of barrels of a liquid slurry of a given viscosity that can be made from a ton of clay. Clays are often classified as either high- or low-yield. A ton of highyield clay yields more slurry of a given viscosity than a low-yield clay.

The volume occupied by one sack of dry cement after mixing with water and additives to form a slurry of a desired density. Yield is commonly expressed in US units as cubic feet per sack (cu. ft./sk).

a measurement applied to clay dealing with the number of barrels of a set viscosity fluid than can be made from a given quantity of clay.
