3.3.8.2 Using Formula Coefficients Before the results of a formula can be used as an input to another step, you must first perform a run where you have coefficients on which to use a formula. Consequently, a formula result cannot be used unless you have performed a run; obtained coefficients; and calculated a result based on a formula that uses those coefficients. The result of your formula may then be used as an input. All coefficients used in the formula must occur before the step using the formula result. In this example we are using the result of a formula as the input for the
Area of an Irregular Shape (Pentagonal wire). The formula for the cross-sectional area is: Area = x 2 (0.72654) Where x = length of pentagon side
A formula is used to find a result (Area) that is used as the input for the Sample Definition Step 5. The formula uses the Side result from Ask Step 3 as “x”. This value is squared and multiplied by a constant 0.72654. The Gauge Length, in the Sample Definition Step 5 is from the operator response to Ask Step 2.
