To determine the density altitude with the given conditions, a calculation method or table is needed that is not provided. The closest relevant data shows a decrease in air density with altitude but does not help in calculating density altitude based on the specific parameters given.
To determine the density altitude for the given conditions, one would typically use a formula or table that considers the pressure altitude adjusted for non-standard temperature variations. The pressure altitude can be found by correcting the airport elevation for the altimeter setting.
However, since the provided information lacks a direct method or the necessary tables to compute the density altitude and the specific data given does not pertain to a standard calculation method, a precise answer cannot be generated without additional information or tools, such as a flight computer, an app, or a specific density altitude chart.
The closest relevant data mentions a decrease in air density with increasing altitude; however, this does not provide us with a direct method to calculate density altitude based on temperature and pressure reading. Furthermore, information on how to calculate the height of a water column at a given temperature and pressure might be useful in similar contexts of pressure and density relations but is not directly applicable to calculating density altitude.
