ciśnienie atosferyczne wynosi 10Pa na 1m2 ........................ ile to N 2. 4000PA ile to hPa 3. parcie wynosi 1000hPa na 1m2 ile to kN

1 Pa = 1 N/1m² 1 hPa = 100 Pa 1 kPa = 1000 Pa 1 MPa = 1 000 000 Pa     1. p = 10 Pa S = 1 m²   p = F/S  I*S F = p*S  F = 10Pa*1m² F = 10 N ------------   2. 4000Pa = 40 hPa  --------------------------   3. p = 1000 hPa = 100 000 Pa S = 1 m²   p = F/S  I*S F = p*S F = 100000Pa * 1m² = 100 000 N F = 100 kN ---------------
