TuE SPECIFIC HEAT OF ANHYDROUS LIQUID AMMONIA. ... 9.11 Ratio of Specific Heats of Vapor (Gas): 1.3 at 20°C 9.12 Latent Heat of Vaporization: 589 Btu/lb = … Specific heat is a property of substance (the so-called material constant). ratio is fourteen parts of nitrogen to three parts of hydrogen, or about 82% nitrogen and 18% hydrogen. I8 9 March, 1898.] SPECIFIC HEAT OF AMMONIA. 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 . 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. Calculation of thermodynamic state variables of ammonia. 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. The commercial product known as ammonia consists of a solution of ammonia gas in water, in strengths varying up to about 5 per cent. 565 btu/lb. At atmospheric temperature and pressures, anhydrous ammonia is a pungent colorless gas. Specific impulse: 343 s. Specific impulse sea level: 294 s. Location: 1785. Anhydrous Liquid Ammonia. What is the absorbent in an ammonia refrigeration system? Ammonia is incompatible with copper, zinc, or copper-based alloys, and corrosion of these metals will occur. 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. This relatively benign propellant combination was used in the XLR-99 rocket motor that powered the X-15 manned rocketplane in the 1960's. ; 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. Also, it depends on external conditions: pressure and temperature. Lox/Ammonia propellant. INTRODUCTORY. 329 constant, so that the specific heat so obtained is at constant volume.5 This specific heat is denoted by cvu. AMMONIA, ANHYDROUS AMA CAUTIONARY RESPONSE INFORMATION Common Synonyms Liquefied compressed gas Colorless Ammonia odor Floats and boils on water. Calculate online thermodynamic and transport properties of ammmonia based on industrial formulation (formulated in Helmholtz energy) for advanced technical applications. 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. Optimum Oxidizer to Fuel Ratio: 1.4. * BY LouIs A. ELL~aU, M.E., NEW YORK, AND WILLIAM D. ENNIS, M.E.. LONO BRANCtL N. J.
