Here are some easy techniques for calculating the time
to dump fuel, or to calculate how much fuel has been dumped in flight.
These tend to be easier problems to work in your head
because there are usually only three variables dump rate, time, and fuel dumped
to use in the formula.
Fuel Dumped/ Dump Rate = Time
Dump Rate X Time= Fuel Dumped

This is a strictly mathematical approach to that some
can readily calculate in their head.
