Calculate the height, in feet, of a column of water that would exert the same pressure as a column of mercury that

is 754 mm high. (The density of mercury is 13.6 g/cm3 and the density of water is 100 g/cm3.)

3 answers

1 inch = 254 mm
• Convert 754 mm Hg to inches Hg
• Convert the inches Hg to feet Hg (1 feet = 12 in)
• Multiply feet Hg to feet H2O by multiplying by 13.6 ft.H2O/ftHg

3.36 ft

874
