Question

The lowest sea level air pressure ever recorded was 870 mb in the eye of Typhoon (Tip) over the Pacific Ocean, whereas the highest sea level air pressure ever recorded was 1084 mb at Siberia associated with an extremely cold air mass." Using Table 9.1 in your e-text complete the following table.

	870 mb	1084 mb
pascal (Pa)
atm
psi
mmHg (torr)

Answer 1

870 mb = 870 millibar

Part a = 870 mb x 100 Pa/1 mb = 87000 Pa

Part b = 870 mb = 87000 Pa x 1 atm/101325 Pa = 0.8586 atm

Part C = 870 mb = 0.8586 atm x 14.7 psi/1 atm = 12.622 psi

Part d = 870 mb = 0.8586 atm x 760 mmHg/1 atm = 652.55 mmHg

Similarly for 1084 mb

1084 mb = 1084 millibar

Part a = 1084 mb x 100 Pa/1 mb = 108400 Pa

Part b = 1084 mb = 108400 Pa x 1 atm/101325 Pa = 1.0698 atm

Part C = 1084 mb = 1.0698 atm x 14.7 psi/1 atm = 15.726 psi

Part d = 1084 mb = 1.0698 atm x 760 mmHg/1 atm = 813.06 mmHg
