no title provided Part A The barometer shown here (Figure 1) measures atmospheric pressure in millimeters of mercury (mmHg). According to this barometer, what is the atmospheric pressure P in inches of mercury (inHg) Part B At a pressure of 919mbar , what would the height of the mercury in the column of a mercury barometer?Explanation / Answer
a) 1inch=25.4mm
therefore, 753.4 mm of hg is equal to 753.4/25.4 inhg
= 29.661 inhg
b) 1 bar = 1000 mbar = 750mmhg
therefore 919 mbar = 750*919/1000
=689.25
