Use Equation 2 or 3 below (or Equation 4 or 5 for greater accuracy) to find the saturation vapour pressure from ambient temperature Use Equation 1 to calculate. Thank you to National Endowment for the Humanities for funding this website and making the project possible. The pressure dew point means the temperature to which the compressed air can be cooled without condensate precipitating. This approach focuses primarily on storage, condition surveys, and the development and implementation of best-fit environment-based strategies. It also addresses specific issues for motion-picture film, sheet film, still roll film, microfilm, and aerial film, as well as the management of collections containing a variety of media types (certainly the most common real-life situations encountered in the field). It addresses the requirements for preserving black-and-white and color film and nitrate, acetate, and polyester-based film. Therefore, if you know an air stream’s dew point at a given pressure, then change the pressure, the dew point will change. Ensure its long-term preservation through appropriate storageį is a central resource for best practices in film preservation that provides guidelines for dealing with the preservation of all types and formats of film materials. Dew point changes as pressure changes (and vice-versa).Learn about environment suitability guidelines.Learn to identify film bases, types, and materials.
