Hyperloop Pod in Tube

About this project

To find the drag for a Hyperloop pod, 1.8m dia, in a 2.6m tube. With the 2:1 tube/pod area ratio, the airflow in the narrow throat is faster or more compressed. The vacuum, about 100Pa (1/1000 atm), will reduce the drag forces. Would like speeds up to 250 m/s, but it's challenging with maybe transonic flow in the throat.
