Pressure in a R-407C cylinder

[Frigorista]

Hi guys,

I have a bet with a friend. The question is:

We have a cylinder with R-407C in a store at 25ºC. Initially the cylinder is full of liquid, and we start to leak refrigerant from the cylinder so we have different states with a) 100% liquid, b) 75% liquid, c) 25% liquid and d) 0% liquid. Among the different states we let the cylinder reach the equilibrium temperature with the ambient, having always a temp. of 25ºC before the pressure measurement. We need to know the pressure in the bottle in the states a), b), c), and d). Important: The leak of refrigerant is always in liquid, never vapour, for the blend not to be corrupted.

Does somebody have the answer?

Thank you in advance!
