What happens when the nitrous temperature is too warm?
As temperatures increase, N20 will lose density and trade its liquid for gas. There is always some gas in the nitrous supply tank, and that is a good thing. This gaseous vapor is what is used to push the liquid into the rocket motor during the fill phase, and what the rocket motor uses to force the liquid out of the oxidizer tank into the combustion chamber during the burn. While the vaporous nitrous is good and performs a wonderful task, too much of it will ruin a good thing. It is important to keep the N20 mostly a liquid, as liquid is what the motor runs on.
