Atm Meaning Pressure. The entire gaseous envelope surrounding the earth and subject to the earths gravitational field. P s system pressure.
Standard Atmosphere is mainly used as a reference value for the average atmospheric pressure at sea level. An atmosphere atm is a unit of pressure based on the average atmospheric pressure at sea level. An atmosphere atm equals to the air pressure at the sea level at a temperature of 15 Celsius.
P atm atmospheric pressure.
Gauge pressure can be calculated by the equation. 5ATM will withstand pressures equivalent to about 50 meters or 164 ft under water. The entire gaseous envelope surrounding the earth and subject to the earths gravitational field. 325 at to psi.
