Calculate the force with which the air presses on the surface of the table, which is 1.2 m long and 0.6 m

Calculate the force with which the air presses on the surface of the table, which is 1.2 m long and 0.6 m wide. The atmospheric pressure is assumed to be 100,000 Pa.

Task data: l (length of the taken table) = 1.2 m; b (table width) = 0.6 m; P (assumed atmospheric pressure) = 100,000 Pa.

The force of air pressure on the surface of the taken table can be expressed from the formula: P = F / S, whence F = P * S = P * l * b.

Let’s perform the calculation: F = 100,000 * 1.2 * 0.6 = 72 * 10 ^ 3 N (72 kN).

Answer: Air presses on the table top with a force of 72 kN.
