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. Viscose is the most natural of the synthetic fibers because itâs made from the cellulose from plant cells. After being dissolved out for spinning into thread it returns to being pure cellulose without chemical alteration.Viscose can be manufactured plain or shiny, as required.Depending on its sheen, delicate qualities or curliness, viscose can therefore look like silk, cotton or wool, and even typical linen fibers can be easily reproduced. Viscose characteristics: Viscose is more absorbent than cotton but not as robust when wet.epending on its sheen, delicate qualities or curliness, viscose can therefore look like silk, cotton or wool, and even typical linen fibers can be easily reproduced.
