What density is associated with vapor R717 at a temperature around 89 degrees?

• A. 0.0270 lbs./ft3
• B. 0.0269 lbs./ft3
• C. 0.0255 lbs./ft3
• D. 1.6915 lbs./ft3

Answer: (A)

The density of vapor R717, which is also known as ammonia, is influenced by its temperature and pressure conditions. At around 89 degrees Fahrenheit, the correct density for vapor R717 is approximately 0.0270 lbs/ft³. This value aligns with typical density values for ammonia gas at this temperature, reflecting the behavior of gaseous refrigerants where density is generally lower at elevated temperatures. Vapor density is a crucial parameter in refrigeration systems, affecting the design and efficiency of different components including evaporators and compressors. Knowing the right density helps operators ensure proper system function and make informed decisions regarding refrigeration cycle calculations. The density values of the other options do not correspond with the expected density for R717 at this temperature, making them less relevant for practical applications in industrial refrigeration.
