One atmosphere (1 atm) of pressure is equivalent to which of the following? 1. 29.9 in Hg 2. 14.7 lb/in2 3. 1034.0 g/cm2 4. 760.0 mm Hg
 
  a. 1, 2, and 3
  b. 2 and 4
  c. 1 and 3
  d. 1, 2, 3, and 4

Question 2

You obtain a mercury barometric reading of 760 mm Hg at 17 C. Using the following factor ta-ble, compute the corrected pressure.
 
   C 740 750 760
  17 2.17 2.20 2.23
  18 2.29 2.32 2.35
  19 2.38 2.41 2.44
 
  a. 223.0 mm Hg
  b. 747.7 mm Hg
  c. 757.8 mm Hg
  d. 762.3 mm Hg

Answer to Question 1

ANS: D
At sea level, the average atmospheric pressure will support a column of mercury 76 cm (760 mm) or 29.9 in in height. If we also know that mercury has a density of 13.6 g/cm3 (0.491 lb/in3), then the average atmospheric pressure (PB) is calculated as follows:
cgs units: PB = 76 cm  13.6 g/cm3 = 1034 g/cm2
fps units: PB = 29.9 in  0.491 lb/in3 = 14.7 lb/in2

Answer to Question 2

ANS: C
The U.S. Weather Bureau provides temperature correction factors for barometric readings (see Appendix 1).

Did you know?

Pink eye is a term that refers to conjunctivitis, which is inflammation of the thin, clear membrane (conjunctiva) over the white part of the eye (sclera). It may be triggered by a virus, bacteria, or foreign body in the eye. Antibiotic eye drops alleviate bacterial conjunctivitis, and antihistamine allergy pills or eye drops help control allergic conjunctivitis symptoms.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

Chronic marijuana use can damage the white blood cells and reduce the immune system's ability to respond to disease by as much as 40%. Without a strong immune system, the body is vulnerable to all kinds of degenerative and infectious diseases.
