How to Calculate Total or Absolute Pressure?
Total or Absolute Pressure calculator uses Absolute pressure = (Mass Density*[g]*Wave Height*cosh(2*pi*(Distance above the Bottom)/Wavelength)*cos(Phase Angle)/2*cosh(2*pi*Water Depth/Wavelength))-(Mass Density*[g]*Seabed Elevation)+Atmospheric Pressure to calculate the Absolute pressure, The Total or Absolute Pressure is the pressure of having no matter inside a space, or a perfect vacuum. Measurements taken in absolute pressure use this absolute zero as their reference point. Absolute pressure is denoted by Pabs symbol.
How to calculate Total or Absolute Pressure using this online calculator? To use this online calculator for Total or Absolute Pressure, enter Mass Density (ρ), Wave Height (H), Distance above the Bottom (DZ+d), Wavelength (λ), Phase Angle (θ), Water Depth (d), Seabed Elevation (Z) & Atmospheric Pressure (Patm) and hit the calculate button. Here is how the Total or Absolute Pressure calculation can be explained with given input values -> 108016.1 = (997*[g]*3*cosh(2*pi*(2)/26.8)*cos(0.5235987755982)/2*cosh(2*pi*1.05/26.8))-(997*[g]*0.8)+101325.
