Chapter 7, Problem 7.28Q
Interpretation Introduction
Interpretation:
The plastics should be determined which are superior to painted plastics due to the distribution of color throughout the product.
Concept introduction:
Colorants are a type of additive used to give a color to a polymer. In the manufacturing process of plastics, colorants are added to get a color.

Chemical Engineering
Use the psychrometric chart and demonstrate the linear interpolation method to obtain -0.52 KJ/KgDA. This is the enthalpy deviation.
The exercise is uploaded below.
Chemical Engineering
Use the psychrometric chart.
The remaining curves on the psychrometric chart are almost vertical and convex to the left, with labeled values (on Figure 8.4-1) of 0.05, 0.1, 0.2, and so on. (The units of these numbers arekJ/kg DA). Thesecurves are usedto determine theenthalpyof humid air that is not saturated. The procedure is as follows: (a) locate the point on the chart corresponding to air at its specified condition; (b) interpolate to estimate the enthalpy deviation at this point; (c) follow the constant wet-bulb temperature line to the enthalpy scale above the saturation curve, read the value on that scale, and add the enthalpy deviation to it.

A moving bed adsorption column needs to be designed to separate hydrophobic proteins from a fermentation broth. The following adsorption equilibrium data was observed in preliminary isotherm studies. The resin used was activated carbon with a porosity of 0.2. The overall mass transfer coefficient was determined to be 10 h¹, and the ratio of volumetric flow rate of broth to resin is 10.
