Version 1.4 (latest)
New interface that has a new menu that includes the ability to show and hide current equation information, units information, and information about the author(me).

Future Updates coming soon: the ability for the user to change the units.

Version 1.3
New denominator is included in the chamber pressure equation to acount for the volume of the co2 bulb for more accuracy.
dblPSI = 1.183 * (dblTemp + 459.67) * dblGrams / (dblDiameter ^ 2 * dblLength + (0.093 * dblGrams))

Future Updates coming soon: New and helpful interface that is more user friendly.

Version 1.2
Below is the vapor psi equation which is used to determine vapor pressures and to determine the state of the co2. 
dblVapourPSI = 0.0000903 * dblTemp ^ 3 + 0.032572 * dblTemp ^ 2 + 5.155 * dblTemp + 292.54252

Future Updates coming Soon: denominator in the chamber pressure equation to be added to account for the volume of the co2 bulb for more accuracy.


Version 1.1
User is able to input any size container in grams.
Equation is as follows:
dblPSI = 1.183 * (dblTemp + 459.67) * dblGrams / (dblDiameter ^ 2 * dblLength)

Future Updates coming soon: Equation for Vapor Pressure to account
for co2 state.

Version 1.0

Program is working for 12g co2 cartridge, does not take into 
consideration the state of the co2 at any given temperature.

Chamber Pressure Equation is as follows:
dblPSI = 1.183 * (dblTemp + 459.67) * 12 / (dblDiameter ^ 2 * dblLength)

Future Updates coming soon: User input for any size co2 cartridge.
