Solution:The combustion reactions for propane and butane are: (a) Stoichiometric Air RequirementOn the basis of 1 volume of the fuel gas, the propane content requires0.7 Ã (5 + 18.8) = 16.7 vols airand the butane requires0.3 Ã (6.5 + 24.5) = 6.3 vols airHence the stoichiometric air-to-fuel ratio is 23:1.
Rating Newest Oldest. Best Answer: Viscose isnt stretchy, that is why the spandex was added. If you get the small it will likely cling to your torso so if you tend to wear close fitting tops then go for the small.Viscose does not shrink so getting a large could backfire in that throwing it in the wash wont make it any smaller. Good luck.Source(s): I am from a family of seamstresses.f you get the small it will likely cling to your torso so if you tend to wear close fitting tops then go for the small.

Viscose is pretty much the opposite of polyester in every way. Viscose is a kind of rayon that is not made from polymers like polyester is.Viscose is a regenerated cellulose fiber (meaning that it's made from plant material) more like cotton or linen. Viscose rayon is a medium-weight fiber with fair to good strength and abrasion resistance....hat all being said, the reason the shirt says Viscose and not Rayon is because rayon has received a bad name because of the crappy rayon made in the 1970's. Rayon today is so super awesome (a new rayon form is called Modal and it's about the best thing in the universe).
