4 standard atmosphere
An atmosphere defined as follows:a) the air is a perfect dry gas;b) the physical constants are:— Sea level mean molar mass:M0 = 28.964420 x 10-3 kg mol-1— Sea level atmospheric pressure:P0 = 1013.250 hPa— Sea level temperature:t0 = 15°CT0 = 288.15 K— Sea level atmospheric density:ρ0 = 1.2250 kg m-3— Temperature of the ice point:Ti = 273.15 K— Universal gas constant:R* = 8.31432 JK-1mol-1c) the temperature gradients are:Note 1.— The standard geopotential metre has the value 9.80665 m2s-2.Note 2.— See Doc 7488 for the relationship between the variables and for tables giving the corresponding values of temperature, pressure, density and geopotential.Note 3.— Doc 7488 also gives the specific weight, dynamic viscosity, kinematic viscosity and speed of sound at various altitudes.(AN 8)Атмосфера, определённая следующим образом:a) воздух является идеальным сухим газом;b) физические константы воздуха являются следующими:— средняя молярная масса на уровне моря:M0 = 28,964420 x 10-3 кг/моль;— атмосферное давление на уровне моря:P0 = 1013,250 гПа;— температура на уровне моря:t0 = 15°CT0 = 288,15 K— плотность на уровне моря:ρ0 = 1,2250 кг/м3;— температура таяния льда:Ti = 273,15 K;— универсальная газовая постоянная:R* = 8.31432 Дж/моль/К;c) температурные градиенты являются следующими:Примечание 1. Стандартный геопотенциальный метр имеет значение, равное 9,80665 м2с-2.Примечание 2. См. Doc 7488, где указаны зависимости между переменными величинами и даны таблицы, содержащие соответствующие значения температуры, давления, плотности и геопотенциальной высоты.Примечание 3. В Doc 7488 также приводятся удельный вес, динамическая вязкость, кинематическая вязкость и скорость распространения звука на различных абсолютных высотах.International Civil Aviation Vocabulary (English-Russian) > standard atmosphere
