A new technique presents a method of rapid programming of engineering formulas on calculators. The method minimizes debugging and documentation time. Formulas are programmed in only one form and any unknown in the equation can be solved. The technique eliminates algebraic manipulation of formulas. It also facilitates solving difficult equations which only yield to methods of sucessive approximations. Presented here are a flowchart, programs and examples using small, pocket-size, programmable calculators. The method can be adapted to almost all programmables. Using this technique, an equation, such as the Hazen-Williams formula, takes approximately five minutes for programming and documentation.
