We are considering the introduction of a new product

We are considering the introduction of a new product. Currently we are in the 34% tax bracket with a 15% discount rate.This project is expected to last five years and then, because this is somewhat of a fad project, it will be terminated. The following information describes the new project:
Cost of new plant and equipment: $ 7,900,000 Shipping and installation costs: $ 100,000 Unit sales: Year Units Sold  1 70,000 2 120,000 3 140,000 4 80,000 5 60,000 Sales price per unit: $300/unit in years 1–4 and $260/unit in year 5. Variable cost per unit: $180/unit Annual fixed costs: $200,000 per year Working capital requirements: There will be an initial working capital requirement of $100,000 just to get production started. For each year, the total investment in net working capital will be equal to 10% of the dollar value of sales for that year. Thus, the investment in working capital will increase during years 1 through 3, then decrease in year 4.Finally, all working capital is liquidated at the termination of the project at the end of year 5. Depreciation method: Straight-line over 5 years assuming the plant and equipment have no salvage value after 5 years. What are the incremental cash flows for the project in years 1 through 5 and how do these cash flows differ from account
