Gas Filling Calculations

This is my little tool to work out what gas you can get out of bank cylinders into your dive cylibders either by boosting or by decanting.

Source Gas

The source gas is the gas which you are decanting or boosting from I've written it to support upto 4 cylinders (if you need / want more contact me and I'll add some more). You fill these with the volume and pressure of each of your source cylinders, it doesn't matter what order you enter them in as the software puts them in assending pressure order.

The total gas is the total free volume of gas in the cylinder and the end pressure is what left after you've decanted or boosted. Pressing the "Copy Pressures to Source" button takes the end pressure and replaces the current pressure for the source cylinders.

Filling details

The filling details section is where you put in the size and pressure for your target cylinder, the min boost pressure is the minimum that your booster will drain a cylinder to, required pressure is the pressure you want and the current oressure is what's in there right now.

Progress

Finally we have the pressure you should get after you've used each source cylinder, if the cylider isn't used then there is no value assigned to it.
