Asked by Katie
The gauge pressure at the bottom of a vertical tube (open to the atmosphere) filled with mecury is 100kPa. How high is the column of mecury in the tube?
I used the formula pressure=density * gravity * height which i reaaranged to find h= 100000Pa/(13570kg/m3*9.8)=0.75m but this is not the correct answer, can anyone help me out

100 kPa is 0.987 atm. If that is the gauge pressure there, the absolute pressure there is 1.987 atm.
