Based on the calculations, the absolute pressure in the pipe is equal to 90,670.4 N/m².
<h3>How to calculate the absolute pressure?</h3>Mathematically, absolute pressure can be calculated by using this formula:
<u>Scientific data:</u>
Atmospheric pressure (Patm) = 1 bar = 1 × 10⁵ N/m²
Head (h) = -70mmhg = -0.07 m hg
Acceleration due to gravity = 9.8 m/s²
Density of mercury = 13,600 kg/m³.
Next, we would determine the gauge pressure:
Now, we can calculate the absolute pressure:
Absolute pressure = 90,670.4 N/m².
