To develop this problem it is necessary to apply the concepts performed to the absolute pressure based on the reference pressure (atmospheric) and the pressure that is generated due to the height of the column of the measured liquid.
In mathematical terms the previous concept can be expressed as
Where
Atmospheric Pressure
Density
g = Gravitational acceleration
h = Height
Our values are given as
g = 9.8m/s
Replacing we have then that
Therefore the absolute pressure in the test section is 99.9019kPa
