Standard sea level

Standard Sea Level (SSL) (also known as Sea Level Standard (SLS)) defines a set of 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:

• Pressure, P = 101,300 Pa = 2116 lbf/ft²
• Density, \(\rho\) = 1.225 kg/m³ = 0.07647 lb/ft³ = 0.002377  slug/ft³
• Temperature, T = 288.16 K = 518.69 °R
• Gas constant of air, R_air = 286.97 m²/(s²·K) = 1716 ft²/(s²·°R)
• Dynamic viscosity, \(\mu\) = 1.79×10⁻⁵ Pa·s = 3.737×10⁻⁷ slug/(s·ft)
