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:〔''Aerodynamics, aeronautics, and flight mechanics'' by Barnes Warnock McCormick Edition: illustrated Published by Wiley, 1979 Original from the University of Michigan Digitized Dec 14, 2007 ISBN 0-471-03032-5, 978-0-471-03032-4 652 pages〕 * Pressure, ''P'' = 101.325 kPa = 2116.2 lbf/ft2 = 14.696 lbf/in2 * Density, = 1.225 kg/m3 = 0.002377 slug/ft3 * Temperature, ''T'' = 288.15 K = 518.67 °R * Gas constant of air, ''R''air = 287.057 m2/(s2·K) = 1716.59 ft2/(s2·°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 at sea level, ''g0'' = 9.807 m/s2 = 32.174 ft/s2 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「standard sea level」の詳細全文を読む スポンサード リンク
