The volumetric analysis of a mixture of gases is 30 percent oxygen, 40 percent nitrogen, 10 percent carbon dioxide, and 20 percent methane. this mixture flows through a 1.6-cm-diameter pipe at 8000 kpa and 15°c with a velocity of 5 m/s. determine the volumetric and mass flow rates of this mixture (a) treating it as an ideal gas mixture, (b) using a compressibility factor based on amagat's law of additive volumes, and (c) using keys pseudo critical pressure and temperature.
the formula for converting between temperature scales is often one of the formulas printed on the inside of one of the covers of your physics text book. (why do i get the creepy feeling that i need to explain what a 'book' is now ? )
anyway, be that as it may, and it probably is, the formula to take a fahrenheit temperature and convert it to a celsius one is
°c = (5/9) x (°f - 32°)
°c = (5/9) x (125° - 32°)
°c = (5/9) x (93°)
°c = (51 and 2/3)°
therefore, elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements. as a general rule, a main group element (except hydrogen or helium) tends to react to form a closed shell, corresponding to the electron configuration s2p6.
