What is the atmospheric pressure?

The atmospheric pressure is133.32kpa. According to the formula of liquid pressure p = P=ρgh, p =13.6×10.3kg/m3× 9.8n/kg× 0.76m =10/3.

Extended data ① The pressure produced by the atmosphere on the objects immersed in it is called atmospheric pressure, which is referred to as atmospheric pressure for short. 1654, Gehrig made a famous experiment in Madeborg, Germany, which effectively proved the existence of atmospheric pressure and made people have a profound understanding of atmospheric pressure.

② Pressure of the object: p=F/S (when using the international system of units, the unit is pa). When the stress area is fixed, the greater the pressure, the more obvious the effect of pressure. (At this time, the pressure is proportional to the pressure) Under the condition of constant pressure, increasing the stress area can reduce the pressure; Reducing the stress area can increase the pressure.
