1) Enter the tank size in gallons.
2) Elasped time for the tanker to travel 200' to the dump site, dump and travel 200' from the site.
3) Elasped time for the tanker to travel 200' to the fill site, fill and travel 200' from the site.
Notes:
1) The "decimal time" is calculated by dividing the seconds by 6.
2) The ISO formula deducts 10% of the tank capacity for spillage, underfilling and incomplete dumping.
(ISO can modify the deduction for vacuum tankers but the 10% is deducted in these calculations.)
