What is Pressure ?

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Various units are used to express pressure.

FAQ

What is Pressure at any point with origin at free surface?
The Pressure at any point with origin at free surface is defined as pressure in rotating fluid about the axis and is represented as Pabs=Patm+(y/[g])*(0.5*(ω*r s)^2)-ω*h or Absolute Pressure=Atmospheric Pressure+(specific weight of liquid/[g])*(0.5*(Angular Velocity*radial distance)^2)-Angular Velocity*Height. Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth, The specific weight of liquid is also known as the unit weight, is the weight per unit volume of the liquid. A commonly used value is the specific weight of water on Earth at 4°C, which is 9.807 kN/m3 or 62.43 lbf/ft3, The angular velocity refers to how fast an object rotates or revolves relative to another point, i.e. how fast the angular position or orientation of an object changes with time, The radial distance is considered in the stagnation point and Height is the distance between the lowest and highest points of a person standing upright.
How to calculate Pressure at any point with origin at free surface?
The Pressure at any point with origin at free surface is defined as pressure in rotating fluid about the axis is calculated using Absolute Pressure=Atmospheric Pressure+(specific weight of liquid/[g])*(0.5*(Angular Velocity*radial distance)^2)-Angular Velocity*Height. To calculate Pressure at any point with origin at free surface, you need Atmospheric Pressure (Patm), specific weight of liquid (y), Angular Velocity (ω), radial distance (r s) and Height (h). With our tool, you need to enter the respective value for Atmospheric Pressure, specific weight of liquid, Angular Velocity, radial distance and Height and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Absolute Pressure?
