5 Prediction of Condensation
5.1 Procedures to Predict Condensation
(b) Find D T and D Pw across each layer from the individual resistance using D T/Rt and D Pw/Rvt.
(c) Establish T and Pw at each layer boundary.
(d) Calculate the humidity ratio from Pw and Pat.
(e) Read corresponding dew-point temperature from psychrometric chart.
(f) Plot the dewpoint and structural temperature curves as shown in Figure 9.
(g) Check whether any condensation occurs or the dewpoint curve is kept above the dry bulb temperature curve.
