n: The boundary between the crust and the mantle of the Earth, which varies from approximately 5 km [3 miles] under the midoceanic ridges to 75 km [46 miles] deep under the continents. This boundary, commonly called the Moho, was recognized in 1909 by Croa

a plotted relationship that predicts shear stress levels at various envelopes of effective normal stress.

n: the volume occupied by one mole of a substance.

n: the vertical distance from the baseline of a ship or offshore vessel to the underside of the deck plating at the side. measured at the midlength of the vessel.

n pi: the dimensions of a vessel to the molded lines.

n: the depth of the vessel below the waterline, measured vertically from the baseline to the waterline.

n: the volume of a compartment without deduction for internal structure or fittings.

n pi: synthetic zeolites packaged in bead or pellet form for (I) use in recovering contaminants or impurities from liquid and vapour product streams by selective adsorption and (2) use as a catalyst.

n: when drilling , the rotary table pass the energy to the pipeline and drive the bit to crush the rock, the volume is subjected to the force of torque.

n: an instrument that reports the performance of a control device or signals if unusual conditions appear in a system. For example. an S&W monitor provides a mechanical means of preventing contaminated oil from entering the pipeline by detecting the presence of excessive water and actuating valves to divert the flow back to dehydration facilities. The monkey board provides a small platform to raise the derrickhand to the proper height for handling the top of the pipe.
