INTRODUCTORY. 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 . 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. Figure 1. illustrates the process of a simple heat pump in a log(P),h-diagram, where the desuperheater part is marked. 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. ... 9.11 Ratio of Specific Heats of Vapor (Gas): 1.3 at 20°C 9.12 Latent Heat of Vaporization: 589 Btu/lb = … I8 9 March, 1898.] Calculation of thermodynamic state variables of ammonia. Ammonia in water solution is called aqua ammonia or ammonium hydroxide. * BY LouIs A. ELL~aU, M.E., NEW YORK, AND WILLIAM D. ENNIS, M.E.. LONO BRANCtL N. J. Ammonia is incompatible with copper, zinc, or copper-based alloys, and corrosion of these metals will occur. Specific impulse: 343 s. Specific impulse sea level: 294 s. Location: 1785. Calculate online thermodynamic and transport properties of ammmonia based on industrial formulation (formulated in Helmholtz energy) for advanced technical applications. This relatively benign propellant combination was used in the XLR-99 rocket motor that powered the X-15 manned rocketplane in the 1960's. Optimum Oxidizer to Fuel Ratio: 1.4. SPECIFIC HEAT OF AMMONIA. Determining the heat transfer area in a heat exchanger for a specific heat pump is critical for obtaining the desired working conditions. What is the absorbent in an ammonia refrigeration system? 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. ; 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 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. Lox/Ammonia propellant. lower limit for calculation: -50 C, 1 bar upper limit: 300 C, 500 bar. At atmospheric temperature and pressures, anhydrous ammonia is a pungent colorless gas. ratio is fourteen parts of nitrogen to three parts of hydrogen, or about 82% nitrogen and 18% hydrogen. TuE SPECIFIC HEAT OF ANHYDROUS LIQUID AMMONIA. Also, it depends on external conditions: pressure and temperature. Temperature of Combustion: 3,090 deg K. Ratio of Specific Heats: 1.23. counter flow heat exchanger to achieve the highest outlet temperature on the secondary media. AMMONIA, ANHYDROUS AMA CAUTIONARY RESPONSE INFORMATION Common Synonyms Liquefied compressed gas Colorless Ammonia odor Floats and boils on water. Anhydrous Liquid Ammonia. Anhydrous ammonia boils at -28° F and fre ezes to a white crystalline mass at … ... What is the latent heat of ammonia at 5 F? 329 constant, so that the specific heat so obtained is at constant volume.5 This specific heat is denoted by cvu. Ammonia, especially in the presence of moisture, reacts with and corrodes copper, zinc, and many alloys. Specific heat is a property of substance (the so-called material constant). 565 btu/lb. The commercial product known as ammonia consists of a solution of ammonia gas in water, in strengths varying up to about 5 per cent.
