If you have scheduled a Cavern or Cave class with me please go through this page. Watch and understand the videos, look at and understand the Powerpoints and the .pdfs I have posted here. If you are already certified and have "forgotten" how to do these things, look over and understand these videos and documents.
Complete all the waivers, agreements andThe Medical Questionnaire and determine whether or not you need medical clearance. Please e-mail me all of the completed documents prior to day one of class.
Videos for gas math
The above video of dissimilar volumes is critical for you to understand and be able to complete the calculations independently.
The above image shows how to calculate dissimilar volumes in metric. Calculating the big tanks turn pressure is done mathematically by: 67 bar useable pressure in the controlling "SMALL" tanks multiplied by the total volume of the "SMALL" tanks (26L) and then divided by the total volume of the "BIG" tanks (34L).
