The MAASP is taken as the most limiting of these. The following example is for the 'B' annulus of a gas lifted well, filled with 1.2 sg brine from the shoe at 4070ftTVD (true vertical depth) to surface.
Consider two wells, X and Y. Well X has a measured depth of 9,800 ft and a true vertical depth of 9,800 ft while well Y has measured depth of 10,380 ft while its true vertical depth is 9,800 ft. To calculate the hydrostatic pressure of the bottom hole, the true vertical depth is used because gravity acts (pulls) vertically down the hole. [2]
B or b – prefix denoting a number in billions; BA – bottom assembly (of a riser) bbl – barrel bbl/MMscf – barrels per million standard cubic feet
In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.
Montevideo units can be more simply calculated by summing the individual contraction intensities in a ten-minute period, a process which should arrive at a result identical to the original method of calculation. [2] Generally, above 200 MVUs is considered necessary for adequate labor during the active phase.
The Mach number (M or Ma), often only Mach, (/ m ɑː k /; German:) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound.

Center of pressure is used in sailboat design to represent the position on a sail where the aerodynamic force is concentrated.. The relationship of the aerodynamic center of pressure on the sails to the hydrodynamic center of pressure (referred to as the center of lateral resistance) on the hull determines the behavior of the boat in the wind.
