n: a kind of tongs used on drill string and casing string with large weight

n: refer toultra-light weight cement

n: the gross weight or pressure applied on the bit to break the rock through ingoing bir

n: the percent ratio of the wieght of gas in a tank to the weight of water that the tank will hold.

n: Cement slurry gets dense furtherly and loses the plasticity whith certain physical strength and can resist certain pressure




a reference to one of many expectations on when cement is sufficiently set to bear some type or level of weight.

n: a kind of tool which can make gas frame with molecular weight surround the electron beam so as to reduce the scattering of the electron beam and improve the ability of beaking rock

n: a tank in which the roof floats freely on the surface of the liquid contents except at low levels, when the weight of the roof is transmitted by its supporting legs to the tank bottom.

n: the depth of submergence of a buoyant automatic gauge float in a liquid of known density or weight.

n: the unit weight of a fluid, e.g., pounds per gallon.

The mass per volume density of a fluid.

n: on a mechanical engine governor, one of usually two small metal weights that spin as the engine runs. When the engine speeds up, centrifugal force on the spinning flyweights increases, which causes a spring to compress and slow the engine down. Conversely, when the engine slows down, centrifugal force on the flyweights decreases which causes the spring to expand and speed the engine up.
