43 inHg = 43 inHg*2.54cm/in = 109.22cmHg * 10 mm/cm = 1092.2 mmHg

14.7 psi = 760 mmHg

1092.2mmHg * 14.7psi / 760 mmHg = 21.13 psi

Answer: option D. 21.13 psi

Answer:

D. 21.13 psi

Explanation:

Given:

Pressure = 43 inches Hg

There are various units for measuring pressure, this includes:

atmosphere (atm), mmHg (millimeter mercury), Pa (pascals), psi(pounds per square inch)

Unit conversion:

1 in Hg = 0.491 psi

Therefore, 43 in Hg would be:

$=\frac{43 in. Hg*0.491 psi}{1 in.Hg} =21.11 psi$
