Ivanhoe Company operates a small factory in which it manufactures two products: C and D. Production and sales results for last year were as follows. C D Units sold 8,900 19,500 Unit selling price $93 $77 Unit variable costs 52 40 Unit fixed costs 21 21 For purposes of simplicity, the firm averages total fixed costs over the total number of units of C and D produced and sold. The research department has developed a new product (E) as a replacement for product D. Market studies show that Ivanhoe Company could sell 11,700 units of E next year at a price of $113; unit variable costs of E are $42. The introduction of product E will lead to a 12% increase in demand for product C and discontinuation of product D. If the company does not introduce the new product, it expects next year's results to be the same as last year's. Compute company profit with products C & D and with products C & E. Net profit with products C & D $ Net profit with products C & E $ Should Ivanhoe Company introduce product E next year? Yes

2. A suspension of particles having an average density of 1200 kg/m³ is to be treated in a sedimentation tank designed with an overflow rate (critical settling velocity) of 13.0 m³/(m²d) and 15°C. The particle size distribution is given in the table below and only Type I settling occurs. It is highly recommended you do this problem using a spreadsheet, such as Excel. a) Determine the total mass fraction removed by the sedimentation tank if the shape factor is 1.00 b) Plot the influent and effluent particle size distribution result from part (a). c) Determine the total mass fraction removed by the sedimentation tank if the particles are disc shaped. d) Plot the influent and effluent particle size distribution result from part (c).

Pre-Lab Activities 1. Tissues are composed of cells and a matrix (extracellular material). The matrix is composed of fibers and ground substance (or, generally speaking, extracellular fluid, interstitial fluid, or tissue fluid). What cells are commonly found in (fibrous) connective tissues? 2. What are the three types of protein fibers found in (fibrous) connective tissues? 3. How is the consistency of ground substance in (fibrous) connective tissues (e.g. fluid, gelatinous, rubbery, or stony)? 4. Identify and label cells, ground substance, and fibers in these two examples of fibrous connective tissues (Note: You will see more types of connective tissues during the lab containing different densities of fibers and different types of ground substance) Areolar Connective Tissue Dense Irregular Connective Tissue
