A related factor is the specific gas constant or individual gas constant. This may be indicated by R or Rgas. It is the universal gas constant divided by themolar mass(M) of a pure gas or mixture. This constant is specific to the particular gas or mixture (hence its name), while the...
R: Gas universal constant, which is equal to 8.31 JKelvin.mol or 0.082 Litre.atmKelvin.molor 10.732 psift3Rankine.mol.pound T: Temperature of the gas in Rankine (R) or Kelvin (K) The pressure, temperature, and volume of gas can be converted as follows: 1atmosphere=1.013×105Pascal=14.7...
The thermal performance depends on r, on the compression rate, and on factor k = Cp/Cv (Cp: specific heat at a constant pressure and Cv: specific heat at a constant volume). In theory, considering that the ratio PCI/(1 + Va) for gasoline is 960 and for methane it is 836, the ...
temperature. What is the final air pressure in the tank? (Answer: 50.0 atm) 4. How many cubic meters of dry air, initially at 1.00 atm, must be pumped into a 50.0-L steel tank at constant temperature so that its final pressure in the tank is 136 atm? (Answer: 6.80 m ...
constant “peak” of force, whereas the slope of the force curve at the contact region determined the stiffness of the sample at each pixel. Other information on the surface mechanics, such as adhesion, deformation, or dissipation, was obtained using the measured cycle of the approach-retraction...
The rate constant for reaction (3a) is given by k3a = 1014.7 ± 0.2 1014.3 ± 1/θ sec1. There are two possible routes for the decomposition of the tert-amyloxyl radical: The dominating process is (3a). From the result at 160°C that k3a/k3b = 80, we arrive at the result ...
Relative to a rate constant for the reaction of OH r... R Atkinson,SM Aschmann,JN Pitts - 《International Journal of Chemical Kinetics》 被引量: 510发表: 1986年 Measurements of acetone and other gas phase product yields from the OH-initiated oxidation of terpenes by proton-transfer-reaction ...
This differential equation relates the real gas pseudopressure (real gas potential) to the time t and the radius r. Al-Hussainy, Ramey, and Crawford (1966) pointed out that in gas well testing analysis, the constant-rate solution has more practical applications than that provided by the ...
气体常数(又称通用气体常数或理想气体常数,通常用符号R表示)是一个在物态方程中联系各个热力学函数的物理常数。(气体常数与阿伏伽德罗常数的比为波尔兹曼常数。)这是表征理想气体性质的一个常数。气体常数相当于玻尔兹曼常数,但以每摩尔每温度增量(而不是每个颗粒每温度增量的能量)表示为能量单位(即压力 - ...
