The Vickers Vimy:
According to Wikipedia2:
We use the range 3,222—4,937 kg, since we do not know at what weight in that range the relevant speeds were measured.
We also have:
From these we can calculate:
Energy use per second
= power of engine x 1/efficiency in converting energy to engine power
= 270kJ/s / .15—270kJ/s / .30
= 900—1800 kJ/s
Wikipedia gives us:
Note that the figures for power do not obviously correspond to the highest measured speed. This is a rough estimate.
We now have (from above):
Thus, on average each second the plane flies 44.7 m and uses 900—1800 kJ, for 0.025—0.050 m/kJ.
This gives us a range of 0.081 – 0.25 kg.m/J
