WebThe boil-off losses from the Dewar occur during the fill and are mostly due to the changes of LH2 volume (total: 14 kg) and the losses from the trailer happen at the end of the fill, when the trailer is depressurized from ~45 psi to 20 psi (total: 14.5 kg). In that calculation, the relief device of the Dewar is set at 30 psi.
