What approximate density is recorded for R717 vapor near 90 degrees?

R717, also known as ammonia, is a common refrigerant used in industrial applications. Its density in vapor form at a given temperature is an important factor for system design and efficiency calculations.

At approximately 90 degrees Fahrenheit, the vapor density of R717 is typically around 0.0270 lbs./ft³. This information is derived from thermodynamic tables and charts for ammonia, which provide critical properties at different temperatures and pressures.

Understanding the density of R717 vapor is essential for operators as it affects calculations related to system capacity, flow rates, and equipment sizing. Factors such as variations in temperature and pressure can also affect the density, but at 90 degrees Fahrenheit, the value you selected is consistent with common industrial references for ammonia properties.
