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.

Gathering viscosity data on a material gives manufacturers the ability to predict how the material will behave in the real world. For example, if toothpaste does not have the correct viscosity, it can either be too difficult to pump out from the tube, or pump out too much. Knowing the viscosity of a material also affects how the production and transportation processes are designed.
