(redirected fromSpecific gas constant) Thesaurus Medical Encyclopedia gas constant n.SymbolR A constant, equal to 8.314 joules per kelvin, 0.08206 liter atmospheres per mole kelvin, or 1.985 calories per degree Celsius, that is the constant of proportionality in the ideal gas law. ...
The specific gas constant and the stoichiometric air fuel ratio of the fuel gas is then determined based on the determined first and second λ value. The present invention also relates to a system for determining the specific gas constant and the stoichiometric air fuel ratio of a fuel gas ...
If you need to calculate the density of dry air, you canapply the ideal gas law. This law expresses density as a function of temperature and pressure. Like all gas laws, it is an approximation where real gases are concerned but is very good at low (ordinary) pressures and temperatures. ...
where μ is the flow coefficient of the high-pressure bleed air duct leakage. A0 is the leakage area. R is the specific gas constant (for air, R = 287.1 J/(kg·K)). p0 is the pressure in the high-pressure bleed air duct. T0 is the temperature of the high-pressure bleed air...

where cp is the specific heat capacity set to 4,000 J kg−1 K−1 and ρo is the mean density of sea water set to 1,026 kg m−3. Unless otherwise stated, we use 1970–1999 as a reference period in the historical simulations and 2070–2099 as the reference period ...
By supposing a pipeline pressure level of 7 MPa and a maximum pressure level of 15 MPa, the specific compression and expansion works together with the heat exchanged in the two heating processes are reported in Table 1 for an ideal case and a real case. For the latter, a compression and ...
In alveolar air, CO2 levels are very constant around 5%; this parameter may therefore be considered as a marker of correct sampling.1 在肺泡空气中,二氧化碳水平非常稳定在5%左右;因此,该参数可以被认为是正确取样的标志。1 4.6 Breath methane excretion might improve the diagnostic accuracy of breath tes...
Therefore, the specific choice of distribution within the family of positive valued exponential distributions should not affect the conclusions of this paper. We choose the Rayleigh distribution as a test case in our simulation model, where the bubble size distribution described by the random variable...
