Questions Fréquentes
Pression (P) = Force (F) ÷ Aire (A). En SI : Pa, N, m².
1 bar = 100 000 Pa. Divisez par 100 000 pour obtenir les bars.
Force = Pression × Aire. Ex. : P = 500 Pa, A = 2 m² → F = 1 000 N.
Un Pascal (Pa) est l'unité SI de pression : 1 N/m².
Divide by 100,000. 1 bar = 100,000 Pa = 100 kPa. Standard atmospheric pressure is approximately 1.01325 bar or 101,325 Pa.
P = F ÷ A, where P is pressure in Pascals, F is force in Newtons, and A is area in m². Rearranged: F = P × A and A = F ÷ P.
Standard atmospheric pressure is 101,325 Pa (approximately 101.3 kPa or 1.013 bar). This is the average air pressure at sea level.
