The pressure exerted by a column of liquid is equal to the product of the height of the column times the gravitational constant times the density of the liquid, P = ghd. How high a column of water (d = 1.0 g/mL)would be supported by a pressure that supports a 713 mm column of mercury (d = 13.6 g/mL)?

Question

Quizplus · Accepted Answer

The pressure exerted by the mercury column is equal to the pressure exerted by the water column. Using the formula P = ghd, and equating the pressures: (13.6 g/mL)(713 mm) = (1.0 g/mL)(h mm), solving for h gives h = 9.7 × 10³ mm.
