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.
Ammonium nitrate-sulfate (30-0-0 + 6.5S) is a dry nitrogen fertilizer relatively new to the United States. It is manufactured by reacting anhydrous ammonia with a mixture of nitric acid and sulfuric acid. The nitrogen content of the product will vary depending on the proportion of nitric to sulfuric acid.he reacted material is concentrated, prilled and coated to prevent caking. In ammonium nitrate, one-half of the nitrogen is in the nitrate form, and the other half is in the ammonium form. Ammonium nitrate is the preferred form of nitrogen fertilizer when it is to be applied on the soil surface and not incorporated.
