Hi.
Of course it depends on weight, altitude and std temp deviation and speed. The following values are not are from FCOM 3, actually noted observations of mine during flight. The avarage Mach no 0.81.
When it is about 200 ton, at FL 370 (that is approximate fuelwise Opt level at Std temp) 2 eng total consumption rate is 100 kg/min (approx).
When it is about 170 ton, at FL 400 (that is approximate fuelwise Opt level at Std temp) 2 eng total consumption rate is 90 kg/min (approx).
So you can calculate Fuel Flow per engine in lbs on your own.
I hope it helps
