3. We learned that a column of mercury in a barometer is around 760 mm in height. We also learned that a water barometer would have to be over 10 m tall. What would be the height of a column of isopropyl alcohol if it were used in a barometer? The density of isopropyl alcohol 785 kg/m3.
Homework Answers
Find the pressure in Pascal and use that to find the height of
alcohol using its density as shown below

Assume that the stick's center of gravity is at its exact center (i.e., Xcg = 50 cm). Draw a diagram of the three forces acting on the meterstick. What are the magnitudes of the upward forces exerted by the two fulcra on the stick? 3....

The column of a mercury barometer is calibrated in linear units
(such as inches or millimeters) and thus the air pressure observed
on such a barometer is reported in terms of these linear units.
This measurement of pressure can be converted to other common
pressure units. Some conversion factors are shown here.
1mm Hg = 1torr
1 atm = 760mm Hg
1 atm = 1.01325 bar

(a) How high in meters must a column of water be to exert a pressure equal to that of a 760-mm column of mercury?
(a) How high in meters must a column of water be to exert a pressure equal to that of a 760-mm column of mercury? The density of water is 1.0 g/mL whereas that of mercury is 13.6 g/mL (b) What is the pressure, in atmospheres, on the body of a diver if he or she is 39 ft below the surface of the water when atmospheric pressure at the surface is 0.97 atm?

In principle many different liquids could be used in a barometer. Mercury is usually preferred by virtue of its low vapour pressure and high density. As part of a school project, you have decided to build a barometer using water. Assuming the maximum pressure that the instrument will need to read is 1.05 atm, determine the height of the column required if (a) you ignore the vapour pressure of water or (b) you take the vapour pressure of water (PH2O=3.17...
