CALCULATION OF THE UNIFORM CASH FLOW WHICH IS EQUIVALENT TO A CUBICALLY VARYING CASH FLOW.

Finding the uniform annual cash flow which is equivalent to a given irregular cash flow is an elementary but frequently arduous calculation. A closed form result is developed from which the uniform annual cash flow may be calculated provided that the actual cash flow varies with time according to a polynomial whose degree does not exceed three. An example which concerns finding the equivalent annual energy dissipation cost in electric system distribution transfomers is included.
