Capillary pressure, as seen in petroleum engineering, is often modeled in a laboratory where it is recorded as the pressure required to displace some wetting phase by a non-wetting phase to establish equilibrium.
Asker's rating. 1  Ammonium nitrate is the chemical compound NH4 NO3. So there would be 3 different elements: nitrogen, hydrogen, and oxygen. 2  Ammonium nitrate is NH4NO3, making it three different elements: nitrogen, hydrogen, and oxygen. mmonkeyccup Â· 1 decade ago. 3  3 elements in ammonnium nitrate, NH4NO3. N from nitrogen, H from hydogen and O from oxygen. NH4 + + NO3---> NH4NO3. The compound consists of 2 polyatomic ions : first, NH4(1 positive charge) which consists of a)Nitrogen and b) Hydrogen, and the second one is NO3 (1 negative charge)consisting of Nitrogen and Oxygen.
Although it is mainly used for fertilizer, it can be used for explosives. It was sometimes used to blast away earth to make farm ponds. Ammonium nitrate is also used to modify the detonation rate of other explosives, such as ammonia-based dynamites, for example nitroglycerin and amatol.mmonium nitrate has a critical relative humidity of 59.4%, above which it will absorb moisture from the atmosphere. Therefore, it is important to store ammonium nitrate in a tightly sealed container. Otherwise, it can coalesce into a large, solid mass. Ammonium nitrate can absorb enough moisture to liquefy.
