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.
The formula to be used is the Barometric Pressure formula:
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/cm3 and 1.00 g/cm3, respectively.
