if a certain pressure supports a 256 column of mecury, how high a column of water would it support?

256 WHAT column of mercury? Is that inches, feet mm, miles? The density of mercury is 13.6 g/cc. The density of water is 1.00 g/cc.

Sorry, its mm of mecury.

To find out how high a column of water a certain pressure would support, we can use the concept of pressure and the density of the liquids involved.

The pressure in a fluid column is given by the formula:

Pressure = Density x Gravity x Height

In this case, we know that the pressure supports a 256-column of mercury. The density of mercury is approximately 13,600 kg/m³, and the density of water is approximately 1000 kg/m³.

We can set up a ratio using the densities to find the height of the water column that would have the same pressure:

Height of mercury column / Height of water column = Density of water / Density of mercury

Let's solve for the height of the water column:

Height of water column = (Height of mercury column x Density of water) / Density of mercury

Substituting the given values:

Height of water column = (256 x Density of water) / Density of mercury

Height of water column = (256 x 1000) / 13600

Height of water column ≈ 18.82 meters

Therefore, the pressure that supports a 256-column of mercury would support a column of water approximately 18.82 meters high.

To determine the height of a column of water that a certain pressure can support, you need to understand the principles of fluid pressure. The pressure exerted by a fluid depends on the height and density of the fluid column. In this case, we are given that a certain pressure supports a 256 cm column of mercury, and we need to find the equivalent column height for water.

First, let's establish a ratio based on the densities of mercury and water. The density of mercury is approximately 13.6 times greater than that of water.

Therefore, to find the equivalent column height of water, we need to divide the height of the mercury column by the density ratio (13.6).

Let's calculate it:

Height of mercury column = 256 cm
Density ratio (water/mercury) = 1/13.6 = 0.0735

Now, divide the height of the mercury column by the density ratio:

Equivalent height of water column = Height of mercury column / Density ratio

Equivalent height of water column = 256 cm / 0.0735

Using a calculator, the approximate equivalent height of the water column would be around 3,488.44 cm, or 34.88 meters.

Therefore, a certain pressure that supports a 256 cm column of mercury would support approximately a 34.88 meters column of water.
