A normal blood pressure reading is less than 120/80 where both numbers are gauge pressures measured in millimeters of mercury (mmHg). What are the absolute and gauge pressures in pascals at the base of a 0.0790 m column of mercury? (The density of mercury is ̑Hg = 13.6 × 10³ kg/m³. Assume the system is at sea level.)
(a) absolute pressure (Enter your answer to at least three significant figures.)
10529.12 Pa
(b) gauge pressure (Enter your answer to at least two significant figures.)
111529.12 Pa
