Bit Rate vs File Size

Newbee here, so please have patience.
I'm involved on a capacity planning project for streaming video. One of our providers is delivering videos at 700k for a 20 minute video.
What file size should I expect to see? Are there standard bit rate / file size?

Appreciate your help

The file size can be determined by:

(length of video in seconds * kbps) / 8

So if you have a 700kbps video that is 20 minutes long (1200 seconds):

(1200 * 700) / 8 = 105,000 Kilobytes

Note the exact number can vary depending on overhead like meta data, variable bitrate video varies too as will the method used for variable bitrate like 2 pass encoding.
