n: total pressure measured from an absolute vacuum. It equals the sum of the gauge pressure and the atmospheric pressure. Expressed in pounds per square inch.

the reading of gauge pressure plus the atmospheric pressure.

n pi: total pressure at a depth underwater, expressed as multiples of normal atmospheric pressure.

n: the total pressure exerted in the wellbore by a column of fluid and any back-pressure imposed at the surface.

n: The ratio of the total pressure of diamond bit and the number of diamond, that is the pressure that a single diamond sustains.

n: a constant number, mathematically the product of the total volume and the total pressure divided by the absolute temperature for 1 mole of any ideal gas mixture of ideal gases at any temperature.

n: the pressure exerted by one specific component of a gaseous mixture.

for CO2 corrosion potential;the mole fraction of the gas times the total pressure.

n: see total pressure. stake a well v: to locate precisely on the surface of the ground the point at which a well is to be drilled. After exploration techniques have revealed the possibility of a subsurface hydrocarbon-bearing formation, a certified and registered land surveyor drives a stake into the ground to mark the spot where the well is to be drilled.

n: the pressure on the surface at which a flowing fluid is brought to rest in excess of the pressure on it when the fluid is not flowing. Also called stagnation pressure.
