PROBLEM 29P

The pressure in Denver, Colorado (5280-ft elevation), averages about 24.9 in. Hg. Convert this pressure to:

(a) Atmospheres

(b) millimeters of mercury

(c) pounds per square inch

(d) pascals

Solution 29P

Here, we are going to convert the given pressure to different units.

Step 1:

Given pressure = 24.9 in. Hg

Converting inches to milimeters, we get,

1 inch = 25.4 mm

Therefore, 24.9 inches = 25.4 x 24.9 mm

= 632.46 mm

Thus, 24.9 in Hg = 632.46 millimeters of mercury.
