Pressure at any Point with Origin at Free Surface Solution

STEP 0: Pre-Calculation Summary
Formula Used
Absolute Pressure = Atmospheric Pressure+(Specific Weight of Liquid/[g])*(0.5*(Angular Velocity*Radial Distance from Central Axis)^2)-Angular Velocity*Height of Crack
PAbs = Patm+(y/[g])*(0.5*(ω*dr)^2)-ω*h
This formula uses 1 Constants, 6 Variables
Constants Used
[g] - Gravitational acceleration on Earth Value Taken As 9.80665
Variables Used
Absolute Pressure - (Measured in Pascal) - Absolute Pressure refers to the total pressure exerted on a system, measured relative to a perfect vacuum (zero pressure).
Atmospheric Pressure - (Measured in Pascal) - Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth.
Specific Weight of Liquid - (Measured in Newton per Cubic Meter) - The Specific weight of liquid is also known as the unit weight, is the weight per unit volume of the liquid. For Example - Specific weight of water on Earth at 4°C is 9.807 kN/m3 or 62.43 lbf/ft3.
Angular Velocity - (Measured in Radian per Second) - 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.
Radial Distance from Central Axis - (Measured in Meter) - Radial Distance from Central Axis refers to the distance between whisker sensor's pivot point to whisker-object contact point.
Height of Crack - (Measured in Meter) - Height of Crack refers to the size of a flaw or crack in a material that can lead to catastrophic failure under a given stress.
STEP 1: Convert Input(s) to Base Unit
Atmospheric Pressure: 101325 Pascal --> 101325 Pascal No Conversion Required
Specific Weight of Liquid: 9.81 Kilonewton per Cubic Meter --> 9810 Newton per Cubic Meter (Check conversion ​here)
Angular Velocity: 2 Radian per Second --> 2 Radian per Second No Conversion Required
Radial Distance from Central Axis: 0.5 Meter --> 0.5 Meter No Conversion Required
Height of Crack: 20000 Millimeter --> 20 Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
PAbs = Patm+(y/[g])*(0.5*(ω*dr)^2)-ω*h --> 101325+(9810/[g])*(0.5*(2*0.5)^2)-2*20
Evaluating ... ...
PAbs = 101785.170802466
STEP 3: Convert Result to Output's Unit
101785.170802466 Pascal --> No Conversion Required
FINAL ANSWER
101785.170802466 101785.2 Pascal <-- Absolute Pressure
