A new and distinct cultivar of Angelonia plant named \u2018Zebra\u2019, characterized by its upright plant habit; freely branching habit; freely flowering habit; and red purple and purple bi-colored flowers. To prevent an occurrence of formations that obstruct the flow of fluid in the fluid conduit, a forecast is made as to whether a flow assurance curve will intersect an operating curve of the fluid conduit. The system may provide the timing schedule by which an operation cycle is implemented consecutively in a group of rows.
