Here, we are asked to calculate the **height **of a water-filled manometer at a pressure of 294 mmHg. Given the densities of Mercury and Water.

- Mercury Density = 16.6 g/cm
^{3} - Water Density= 1.00 g/cm
^{3}

The formula to be used is the **Barometric Pressure ****formula:**

**Where:**

P = pressure

d = density of fluid (*use the density of water since the manometer is water-filled**)*

g = acceleration due to gravity

h = height

How tall must a water-filled manometer be to measure blood pressures as high as 294 mmHg? The densities of Mercury and Water are 13.6 g/cm^{3} and 1.00 g/cm^{3}, respectively.
