Find the height of the column of gasoline that produces bottom pressure equal to atmospheric pressure.
| September 10, 2021 | education
Reference data: P (pressure of the gasoline column at the bottom, atmospheric pressure) = 101,325 Pa; g (acceleration due to gravity) = 9.81 m / s2; by condition ρb (gasoline density) = 710 kg / m3.
The height of the gasoline column can be expressed from the formula: P = ρb * g * h, whence h = P / (ρb * g).
Calculation: h = 101325 / (710 * 9.81) = 14.55 m.
Answer: The height of the petrol column should be 14.55 m.
