UN 2672; Ammonia solutions density (specific gravity) between 0.880 and 0.957 at 15 °C in water with more than 10% but not more than 35% ammonia. Calculation of thermodynamic state variables of ammonia. Ammonia, especially in the presence of moisture, reacts with and corrodes copper, zinc, and many alloys. ratio is fourteen parts of nitrogen to three parts of hydrogen, or about 82% nitrogen and 18% hydrogen. Hazardous Substances Data Bank (HSDB) UN 2073; Ammonia solutions density (specific gravity) less than 0.880 at 15 °C in water , with more than 35% but not more than 50% ammonia . Lox/Ammonia propellant. Anhydrous ammonia boils at -28° F and fre ezes to a white crystalline mass at … This relatively benign propellant combination was used in the XLR-99 rocket motor that powered the X-15 manned rocketplane in the 1960's. Specific heat is a property of substance (the so-called material constant). * BY LouIs A. ELL~aU, M.E., NEW YORK, AND WILLIAM D. ENNIS, M.E.. LONO BRANCtL N. J. What is the absorbent in an ammonia refrigeration system? The subscript v signifying " at constant volume," and the subscripts i and 2, denoting "of a mixture of liquid and vapor," subscript 1 referring to the vapor phase and sub script 2 to the liquid phase. Specific impulse: 343 s. Specific impulse sea level: 294 s. Location: 1785. Also, it depends on external conditions: pressure and temperature. 565 btu/lb. The specific gravity of brine is measured: ... On an ammonia compression system, compression ratio can be described as: The ratio of absolute discharge pressure to absolute suction pressure. Anhydrous Liquid Ammonia. INTRODUCTORY. The commercial product known as ammonia consists of a solution of ammonia gas in water, in strengths varying up to about 5 per cent. Temperature of Combustion: 3,090 deg K. Ratio of Specific Heats: 1.23. Ammonia is incompatible with copper, zinc, or copper-based alloys, and corrosion of these metals will occur. Determining the heat transfer area in a heat exchanger for a specific heat pump is critical for obtaining the desired working conditions. ; The specific heat tells us how difficult it is to heat the given body.Substances with low specific heat change their temperature easily, whereas high ones require much more energy delivered to achieve identical effect. AMMONIA, ANHYDROUS AMA CAUTIONARY RESPONSE INFORMATION Common Synonyms Liquefied compressed gas Colorless Ammonia odor Floats and boils on water. 329 constant, so that the specific heat so obtained is at constant volume.5 This specific heat is denoted by cvu. counter flow heat exchanger to achieve the highest outlet temperature on the secondary media. TuE SPECIFIC HEAT OF ANHYDROUS LIQUID AMMONIA. Figure 1. illustrates the process of a simple heat pump in a log(P),h-diagram, where the desuperheater part is marked. At atmospheric temperature and pressures, anhydrous ammonia is a pungent colorless gas. ... 9.11 Ratio of Specific Heats of Vapor (Gas): 1.3 at 20°C 9.12 Latent Heat of Vaporization: 589 Btu/lb = … Ammonia Data Book 2-5 May 2008 Chapter 2 — Properties of Ammonia Chemical Properties of Ammonia Compatibility Ammonia reacts readily with a wide variety of substances.
