With all 6 Override/Jettison Pumps operating, max dump rate is 2,600
kgs/minute.  There are 2 Jettison/Override pumps in the Centre tank, and
2 Jettison pumps in each of the No 2 & 3 tanks.

Having said that, the most I've dumped is just over 40 tonnes, and it took
a lot longer than the 16 minutes Mr. Boeing said it would :(
