The gas is CO2 (very close to 100% CO2)
V - The Volume of the Cylinder (constant)
P - The pressure of the Cylinder (from a sensor)
T - The temperature of the Cylinder (from a sensor)
I want to know:
How many liters of CO2 remain in the Cylinder. Liters based on the room temperature and pressure. (1atm and room temperature might be a safe assumption)
First I thought I could use the Ideal Gas Laws to calculate this, however, the gas Cylinder is under very high pressure > 1200psi and CO2 will not behave as an ideal gas under these conditions.
How can I solve this using only what I have for sensors? Ex. without adding a scale to measure Cylinder weight. Is it possible?
