Hello, Can some here explain the use of formula In item 18.8.2 of IGC code for the calculation of ESD valve closure time. Formula: 3600 U/LR Where U ullage volume at operating signal level and LR maximum lloading rate.
hi, lets say your U value is 152,88 cbm(vapour space of the tank at required innage level) and LR value is 800cbm/h(loading rate of the tank in cbms) so; CT: 3600/(152,88X800)=29,4sec I hope this might help
