Template:Short description Standard sea-level conditions (SSL),[1] also known as sea-level standard (SLS), defines a set of atmospheric conditions for physical calculations. The term "standard sea level" is used to indicate that values of properties are to be taken to be the same as those standard at sea level, and is done to define values for use in general calculations.
Atmospheric properties
At SSL some atmospheric properties are:[2]
- Pressure, P = 101.325 kPa ⇔ 2116.2 lbf/ft2 ⇔ 14.696 lbf/in2 ⇔ 760 mmHg ⇔ 29.92 inHg
- Density, = 1.225 kg/m3 ⇔ 0.002377 slug/ft3
- Temperature, T = 15 °C ⇔ 59 °F ⇔ 288.15 K ⇔ 518.67 °R
- Gas constant of air, Rair = 287.057 J/(kg·K) ⇔ 1716.59 ft·lb/sl·°R)
- Specific Weight, = 12.014 N/m3 ⇔ 0.07647 lbf/ft3
- Dynamic viscosity, = 1.789×10−5 Pa·s ⇔ 3.737×10−7 slug/(s·ft)
- Acceleration of gravity, g0 = 9.807 m/s2 ⇔ 32.174 ft/s2
