A Standard Atmospheric pressure excerts a force on a Mercury filled glass tube with one end closed to make the metal rise 29.92 inches. In a perfect vacuum environment, theoreticaly, there should be no rise on the column of mercury; answer is zero inches.

About 2 1 pound per square inch = 2.0362... inches of mercury
That could depend on several different factors, such as altitude etc... I do believe that at about sea level its -14.7 psi.
2.9 inches stay 2.9 inches.
There are 100 inches in 8ft 4in
