Straight Line Depreciation

Verink has developed a generalized equation that is particularly adapted to corrosion engineering problems. This equation takes into account the influence of taxes, straight-line depreciation, operating expenses, and salvage value in the calculation of present worth and annual cost. Using this equation, a problem can be solved merely by entering data into the equation with the assistance of compound interest data: (reference)

Present Worth (PW) can be converted to equivalent annual cost (A) by using the following formula:
