Question

What must be in cm, the barometric height so that the pressure is 1000 mbar?Density of mercury: 13.6

Answer 1

75.064 cm

Explanation

to solve this we need to know the equivalence

$1mmbar=0.075006cmHg$

then

let's use a equivalente fraction to convert the measure

$1000\text{ mbar(}\frac{0.075006\text{ cm HG}}{1\text{ mbar}})=75.064\text{ cm Hg}$

hence, the answer is 75.064 cm
