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 rayon is a man-made fiber made from wood pulp though other materials may be used. It is basically modified cellulose. Viscose is very similar to cotton and silk. (Co â¦ tton is also made of cellulose). Viscose falls somewhere in between a natural fiber and a man-made one.The raw material for viscose is cellulose which is usually reacted with caustic soda and carbon disulfide.t is reformed as fibers by spinning this viscose solution in an acid bath. Viscose rayon has a silky appearance and feel, and also has the ability to breathe in a manner similar to cotton weaves.
