Note: this is not a homework question; this is strictly conceptual in understanding the equations at work in this scenario.
The tank is vacuum-insulated, the liquid is saturated, and the vents have just been opened in order to vent down the ullage pressure. My question is simply how do you calculate the rate of boil-off of the liquid (i.e. how much liquid mass evaporates and discharges as gas until it is cooled well below saturation and the ullage pressure is 0 psig) and more imporatantly how much liquid gets used up during that time?
Thanks for any input-
