# Appendix E – Component Details

In the Drill String, Well Geometry and Fluids Tab, when a component is selected from the dropdown menu the user can assign various component details. The type of component that is selected will determine the properties displayed in the lower components grid. The following is a list of the components and a description of their properties which can be viewed in the

**Component Details**box at the bottom of the tab.**SN**: Serial number plays no part in any calculations**Gauge OD**: Gauge OD plays no part in any calculations.**TFA**: Click on the cell to bring up the jets dialog.
