Answer: The pressure 12.2 psi is expressed in millimeters of mercury (mm Hg) as 630.9221 mm Hg.
Explanation:
Given: Pressure = 12.2 psi
According to the standard conversion of units, 14.7 psi = 1 atm = 760mmHg.
Therefore, 1 psi equal to how many mm Hg is calculated as follows.
[tex]14.7 psi = 760 mm Hg\\1 psi = \frac{760}{14.7} mm Hg\\= 51.7149 mm Hg[/tex]
Hence, 12.2 psi will be converted into mm Hg as follows.
[tex]1 psi = 51.7149 mm Hg\\12.2 psi = 12.2 psi \times \frac{51.7149 mm Hg}{1 psi}\\= 630.9221 mm Hg[/tex]
Thus, we can conclude that the pressure 12.2 psi is expressed in millimeters of mercury (mm Hg) as 630.9221 mm Hg.
