2 стандартная атмосфера
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.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)Русско-английский словарь международной организации гражданской авиации > стандартная атмосфера

3 зависимость
* * *Зависимость -- relation, relationship (выражения); function (функциональная); history (обычно временная); law (общеизвестная); variation, trend, behavior, pattern, characteristic (закономерность, характеристика); sensitivity, dependence (обусловленность)This resulted in a time-temperature history of the combustion gases, vastly different from that of the original burner design.Any major systematic deviation from the standard load/life law should have manifested itself in observed misprediction of lives in service.Зависимость между... иThe behavior of the heat transfer coefficient versus flow rate is different here from the classical Nusselt condensation problem.In the simplest option in the program a straight line relationship is taken for temperature rise against mass blow.Зависимость... отStrouhal number dependence of phase angle (Зависимость фазового угла от числа Струхаля)It became evident that the schedule of casing width versus radius is an arbitrary constraint.The lack of response of performance to variations in viscosity can be traced to the fact mentioned in Section 1.Русско-английский научно-технический словарь переводчика > зависимость
