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.

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 comes under both of them as the raw material used for viscose is cellulose which is broken down and forms fibers. Cotton consists of 90% cellulose, so viscose is considered a natural fiber. Viscose is used in making cellophane.Cellophanes are often used in wrapping gifts and food items etc.iscose is soft, absorbent and feels comfortable when worn on the skin. Viscose is used in the preparation of shirts, trousers, diapers, napkins, towels and many other products. Viscous fiber material is present in many home products. Viscose material is softer than cotton and more springy than silk.
