How high should you take a glass tube filled with water so that it creates a pressure of 500 mm Hg?
September 28, 2021 | education
| The water column pressure can be calculated using the formula:
P = ρ * g * h, where P is the pressure of the liquid column (P = 500 mm Hg = 500 * 133 Pa = 66500 Pa), ρ is the density of water (ρ = 1000 kg / m ^ 3), g is the acceleration of gravity (we take g = 9.8 m / s ^ 2), h is the height of the water column.
Let us express and calculate the height of the water column:
h = P / (ρ * g) = 66500 / (1000 * 9.8) = 6.79 m.
Answer: A glass tube with a height of 6.79 m is required.
