Question

Initial System Diagram and Information: Draw and label a system diagram for each of the following system descriptions. Include all information given by using appropriate notations and initial values given. Governing Equations, Unit Conversions and Assumptions: Include the applicable governing equations using the same notation in the diagram, and list all applicable assumptions for the system and use of these governing equations. Show the unit conversions to be used. Calculation Steps: using the governing equations and assumptions as the basis for your calculations, present the calculation steps that lead to the solution of the problem. Intermediate work involving derivations of secondary equations or algebraic rearrangement of equations must also be shown. Do not leave unexplained or non-obvious gaps in your calculation steps.

59. A MSW containing 74% of light materials is shredded and then separated into its light fraction (paper, plastics, and other lighter organics) and heavy fraction (metals and other inorganics) using an air classifier that has a light fraction recovery of 100%. The shredded MSW is fed into the air classifier at a rate of 225 kg/hr. and the material recovery stream leaves the air classifier at a rate of 185 kg/hr. What is the purity of the light material fraction in the material recovery stream?
