With what force does atmospheric air press on a horizontally lying surface measuring 3m * 1.5m?
| February 27, 2021 | education
To find the force of pressure of atmospheric air on a horizontally lying surface, we apply the formula: F = P * S = P * a * b.
Values of constants and variables: Patm – normal atmospheric pressure (Ratm = 101325 Pa); a is the length of the horizontal surface (a = 3 m); b – surface width (b = 1.5 m).
Calculation: F = P * a * b = 101325 * 3 * 1.5 ≈ 456 * 10 ^ 3 H = 456 kN.
Answer: The atmospheric air presses on a horizontally lying surface with a force of 456 kN.
