Electrostatic forces
A charge on the particle affects the path of the particle around the droplet. A neutral charge is required to increase the collision efficiency.
Types of airborne dust capture systems
Finely atomized water sprays
These are normally used at transfer points where there are no excessive turbulence.

Advantages Disadvantages
Water requirement are low tight enclosures are needed for effective system operation

The capital costs are the costs of acquiring major control equipment, accessories, auxiliary equipment and field installation. Operating and Maintenance costs are direct expenses of labour, day to day operating and maintenance, waste disposal costs, and the cost of replacing parts. (Vinit Moody, 1988)
When acquiring new equipment, a cost benefit analysis has to be done and this requires the knowledge of the time value of money. All future investments and expenditures should be reduced to the present value to correctly compare them.
In the case of annual costs paid each year, they can also be translated to the present value. The following equations are frequently used:
FV=PV〖(1+i)〗^n
Equivalent annual costs are determined using the formula,
EAC=((PV*i))/((1-1/(1+i)^n ))
Where: FV= Future Value PV= Present
Various documents such as a project scope statement, one-time cost or recurring cost worksheet can be created to list costs associated with the project. Other methods include the time value of money, which refers to comparing present cash outlays to future expended returns, and a break-even analysis in order to determine economic feasibility.
A capital expenditure is an amount spent to acquire or improve a long-term asset such as equipment or buildings. Usually the cost is recorded in an account classified as Property, Plant and Equipment. The cost (except for the cost of land) will then be charged to depreciation expense over the useful life of the asset.
Along with the Benefit Measurement Method, Constrained optimization method can also be used which involves mathematical approach. Since this method involves the mathematical approach, several calculations are performed in order to take a decision to accept or reject the project. “Mathematical models, also known as Constrained Optimization Methods, are a category of project selection methods, which is a tool and technique of the Develop Project Charter process” (PMP, 2008). Cost-benefit analysis is one of the methods which fall into this category. All the positives and negatives of the project are taken into consideration and then the negatives are carefully excluded from the benefits. Different results are produced for the different projects. The most worthy and financially rewarding option are selected from these results. When employing this method, there are many things that are to be considered such as the impact of the decision on the development of the organization in the future, the length of time the equipment lasts and whether it is possible to do the cost control during the project.
EEC calculated the amount of time involved the anticipation of its cost ($3 million). The timeline in recovering their cost of investment ($2 million) initially for the foundation of this investment any profit made in the future of this investment will be justified as a profit for the company. If EEC can anticipate a fast return on its investment it is a profitable wise decision in making the investment financial, it is considered to be an easier way of formulating investments financially. On the basis of one year all cash flows is added together equal to the sum of $2 million originally invested, then it is divided by the annual cash flow of $500,000. The calculation of the payback period would equal four years. After this time frame any financial proceeds will be considered profitable for the company. I conclude that the timeframe is adequate in comparison of the investment in this worthwhile investment financial venture for the company.
6. Calculate the total cost of each system over a five-year period (cash flow), by year.
Star Appliance is looking to expand their product line and is considering three different projects: dishwashers, garbage disposals, and trash compactors. We want to determine which project would be worth doing by determining if they will add value to Star. Thus, the project(s) that will add the most value to Star Appliance will be worth pursuing. The current hurdle rate of 10% should be re-evaluated by finding the weighted average cost of capital (WACC). Then by forecasting the cash flows of each project and discounting them by the WACC to find the net present value, or by solving for the internal rate of return, we should be able to see which projects Star should undertake.
Our approach to valuing the processing plant can easily be decomposed into three distinct steps first, find the value of the foreseeable free cash flows. Next, calculate the terminal value of the project. Finally, take the present value of those flows. The next few paragraphs walk through each of these steps in order of progression.
The Conch Republic is an organization which produces reputable electronics is seeking to advance one of their current production lines to stay abreast to changing technology. The company is seeking to introduce a new smart phone with the hopes of boosting the company’s revenue and reputation as a smart phone producer. As a person hired to assess the financial undertaking of Conch Republic an overview of the projects planned expense must be generated. However, in order to accomplish this task a capital investment analysis must be conducted in order to determine the projects viability. This will be done by analyzing several things. Those things that must be understood are the projects payback period, the net present value (NPV), internal
As opposed to purchasing new equipment, we could opt to maintain the equipment we currently have, which has an estimated service life of 11 years remaining. We could retain all of our claimed Investment Tax Credit for this purchase, which has two years of depreciation left, and would not be required to invest in any new training for our employees. We would recognize $31,000 in depreciation in present value terms, as well as save an estimated $200,000 in training costs and losses due to lower production during the “learning curve”. I estimate these savings to be approximately one month of payroll to include both the time spent on training, and our reduced production as employees learn how to use the new equipment. Additional detail of this option is provided in Appendix B, C, & D.
Estimated machinery life: 3 years (after which there will be zero value for the equipment and no further cost savings)
A down payment of $70,000 would be required, and a first year interest payment of $45,370 (Exhibit 9). It is expected that the two machines would run at 40% capacity bringing in incremental revenue of $613,225, and incremental operating income of $234,855. The cost breakdown structure and the incremental gains for the laser cutter and water cutter can be seen in Exhibit 10. The ROI at 40% capacity is 33.80% (Exhibit 5), which is well above the banks lending rate. The payback period at 40% capacity is the lowest of all options at 3 years (Exhibit 6). With a score of 30, this option scored the highest against the decision criteria (Exhibit 7). This is largely due strongest cash flow, highest ROI, and emphasis on maintaining a high quality product and excellent costumer service.
Operating expenses includes production costs, such as direct labor, indirect labor, inventory carrying costs, equipment depreciation, materials and supplies used in production, and administrative cost. This was not happening at Alex’s plant. His inventories had increased over the past six or seven months and operational expense also increased. This meant he had a lot of work to do to keep his plant open and he was now aware of it.
these changes in their assumptions would do to the ROI of the proposal and it’s over all profitability. 2) Will the cost in new equipment be returned by an equivalent reduction in
This analysis is done assuming the benefits accrued in the year 2050. The costs are evaluated from the year 2011 – the proposed time of starting the project, while the benefits are calculated from the year 2020 – the expected time of launching the project. The estimated streams of benefits and costs occurring each year between 2011 and 2050 were discounted to their present value and summarized to calculate the benefit cost ratio.
