A 747-136 carries 39,310 Imperial gallons (47,172 US galls)
A 747-236 carries 44,850 Imperial gallons (53,820 US galls)
A 747-436 carries 47,718 Imperial gallons (57,262 US galls)

Average fuel consumption on the P&W engines (-136) on the Take Off
roll is about 9 Metric Tonnes per hour per engine. This power is
applied for between 3 and 5 minutes. Therefore, you are looking at
about 1.8 to 3.0 Tonnes used in the first 3 to 5 minutes. A -236 or
-436 could be 20% more.

Cost of aviation fuel varies from place to place, but a good rule of
thumb figure for a LARGE customer like British Airways is about 60
cents per US gallon. 3 Tonnes equate to about 300 US dollars for the
Take Off.

OK?
