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.

It all depends. There are good viscose rugs and poor quality viscose rugs. Viscose is really rayon. It is not as durable as wool or many artificial fibers that are used to make rugs.However, it dyes well and has a nice sheen to it when used for rugs.It does not do well when wet, so you have to be careful when cleaning it.ow I am not sure why,it is much thinner than the wool rugs but that part is fine by me. I just want it to last and look good for at least 5-7 years. I happened to like the colors on this viscose rug but I can certainly wait since they get new things in every day and wait for a wool one that I like.
