The Mean Arterial Pressure (MAP) calculates mean arterial pressure from measured systolic and diastolic blood pressure values. This is an unprecedented time. It is the dedication of healthcare workers that will lead us through this crisis.

The Euler Number is a dimensionless value used for analyzing fluid flow dynamics problems where the pressure difference between two points is important. The Euler Number can be interpreted as a measure of the ratio of the pressure forces to the inertial forces. The Euler Number can be expressed as Eu = p / (ρ v2) (1)

Fluid flow, the fluid's velocity can differ between any two points, general capacity of the pipes varies on its size. Laminar & turbulent are the types of fluid flow & ideal plastic & real fluid are the types of fluid.
We assume steady flow, and more-or-less constant density. At some location the fluid is moving with velocity v along a streamline with radius of curvature r. Then the local acceleration is v 2 / r, in accordance with the most basic laws of motion. The pressure gradient is then ρ v 2 / r, with lower pressure on the inside of the turn.
The Bernoulli Effect means that: if a fluid (gas or liquid) flows around an object at different speeds, the slower moving fluid will exert more pressure than the faster moving fluid on the object. The object will then be forced toward the faster moving fluid. Definition “For a non-compressible, non-viscous fluid undergoing laminar flow, the sum of the pressure, kinetic and potential energies per unit volume remains a constant at all points along the line of flow” Mathematically represented by P + 1/2.p v 2 + pgh = constant Where P = Pressure g = Acceleration due to gravity (m/s 2) currently accomplished by locating the fluid level in the annulus using a sonic device and then applying a correlation to estimate the density of the gas-cut liquid column above the perforations. This work proposes a flowing bottomhole pressure calculation procedure from fluid level measurements.
Bernoulli's principle can be explained in terms of the law of conservation of energy (see conservation laws, in physics). As a fluid moves from a wider pipe into a narrower pipe or a constriction, a corresponding volume must move a greater distance forward in the narrower pipe and thus have a greater speed. Oct 11, 2018 · Measurement of arterial pressure is one of the most basic elements of patient management. Arterial pressure is determined by the volume ejected by the heart into the arteries, the elastance of the walls of the arteries, and the rate at which the blood flows out of the arteries. This review will discuss the three forces that determine the pressure in a vessel: elastic, kinetic, and ...
This video explains about pressure of liquid i.e. fluid pressure. It shows through experiments that liquid exerts pressure in all direction (upward, downward...of the fluid. For example, we can consider the mean local velocity v(x, y, z, t) of fluid particles or fluid points, called the fluid velocity, and two thermodynamic quantities that characterize the fluid state, the pressure p(x, y, z, t) and the mass density (x, y, z, t), the mass per unit volume of fluid.
