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.

n: the maximum stress that a solid can withstand without undergoing permanent deformation either by plastic flow or by rupture. See tensile strength.
