This brings us back to screening efficiency. After installation it is essential to determine if the equipment is fit for purpose and if it's achieving the client's objectives. Tony favours the use of the Taggart (1966:7-04) formula for this purpose. It is a simple formula and easy to apply:
Simplifying and solving for the flow efficiency, F, we obtain .....(2) where x ≠ 0. The above equation clearly shows that it is possible to obtain flow efficiency rather simply with two stabilized bottomhole pressures and two stabilized flow rates. A similar analysis can be performed to obtain an expression for a linear IPR (x = 0).
The efficiency factor e is equal to 1.0 for an elliptic distribution and is some value less than 1.0 for any other lift distribution. So, an elliptical wing planform has the lowest amount of induced drag and all other wing shapes have higher induced drag than an elliptical wing. For a rectangular wing, the efficiency factor is equal to .7.
This results in a percentage of goods that are unusable. The formula for calculating scrap rate is: Scrap rate = (number of scrap items ÷ total completed items) x 100 Related: Your Guide to the Work-in-Process Formula How to calculate the scrap rate Use the following steps to apply the scrap rate formula: 1. Determine the number of scrap items
You must use the efficiency formula, output divided by input, to calculate efficiency. It will give you a ratio to convert to a percentage by multiplying by 100. For example, if a machine produces 100 units per hour and requires 200 watts of power, the efficiency can be calculated as 100/200 = 0.5 or 50%.
