where Eh is the hydrate reaction activation energy, Rhf is the rate of hydrate formation; R and TR are respectively the universal gas constant and reservoir temperature, hC and Sh are respectively the hydrate concentration and the hydrate saturation, φ and ρh are the porosity and the hydrate...
An aerosol spray can contains a residual gas at 1.05 atm and 20o C. The can is placed in the oven that is set at 325o F. What is the final gas pressure at 325o F? (Assume volume remains constant.) (Answer: 1.56 atm)7. A sample of helium gas has a volume of 56.0 ...
的氣體”。將此與原定義比較可知,新定義除了需要玻意耳定律(Boyle’s Law)和查理定律之外,還必須再加上一條阿伏伽德羅定律(Avogadro’s Law),(2)式中的普適氣體常量(General Gas Constant或Ideal Gas Constant) “R”就是據阿伏伽德羅定律(Avogadro’s Law)求得的。儘管如此,關於理想氣體模型之特點的種種討論仍...

Since PV=nRT (where P denotes a pressure of the pipe portion, V denotes a volume of the pipe portion, n denotes the number of moles, R denotes a constant, and T denotes a temperature of the pipe portion), the number of moles n can be obtained. FIG. 2 shows that (1) the gas ...
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...
