![]() The one that concerns us here relates temperature, humidity, enthalpy, and certain other properties of moist air is called the Psychrometric chart. ![]() Many such charts are used in engineering practice. Air conditioning is not an exact science, and information that is sufficiently precise for the solution of most air conditioning problems can usually be obtained from graphs or charts. Even the use of prepared tables of values is time consuming, since interpolation is often required. ![]() Although engineers and technicians need to know how the values of such properties of air as specific humidity, sensible and latent heat, and relative humidity in our designs, the actual computation of these quantities is much too burdensome for everyday operations. ![]()
