HI All,
I am trying to calculate propylene losses from a double wall storage tank operating at 0.066 kg/cm2g & -42 Celsius.
In the tank calculation sheet its shown that percent losses per day are 0.1548%, this number is derived considering the design liquid level ( maximum level) i.e. 80%.
My question is the loss of propylene is dependent on liquid level in the tank, higher the liquid level higher the losses & vice versa?
