For this equation, the manometer, which is simply a U-shaped tube with fluid inside of it, is filled with water. Water has a known density of 1 kg per liter. External air pressure is 1 atm. If the water rises in one side of the manometer by 10 cm, the difference between the two points is 0.00968 atm.
