If you have those numbers to share, great, otherwise...

  The original proposal is available.[1] It includes enough numbers to make estimates of the physics involved. If you want to see what's essentially two youtubers arguing over the physics involved, check this[2] out. It gets a little petty by the end, but there is copious physics and math demonstrated, which you can assess yourself (along with whether the assumptions they make are valid). They do, specifically, go over what would be required to achieve the level of partial vacuum specified, as well as what would be required to safely achieve controlled rapid pressurization in an emergency. Or you can do a little googling. There's plenty of people that have jumped in with an assessment, and just about as many that have come after to refute some or all of their work. 1: http://www.spacex.com/sites/spacex/files/hyperloop_alpha.pdf http://www.spacex.com/sites/spacex/files/hyperloop_alpha.pdf 2: https://www.youtube.com/playlist?list=PLSPi1JFx4_-Gz0Fm0qq2KUz4c22UbZCco https://www.youtube.com/playlist?list=PLSPi1JFx4_-Gz0Fm0qq2K...
