PROBLEM 31P
The North American record for highest recorded barometric pressure is 31.85 in. Hg, set in 1989 in Northway, Alaska. Convert this pressure to:
(a) millimeters of mercury
(b) atmospheres
(c) torr
(d) kilopascals
Solution 31P
Here, we are going to convert the given pressure to different units.
Step 1:
Given pressure = 31.85 in. Hg
Converting inches to milimeters, we get,
1 inch = 25.4 mm
Therefore, 31.85 inches = 25.4 x 31.85 mm
= 809(approx.) mm
Thus, 31.85 in Hg = 809 millimeters of mercury.
