Part time coconut farmer here.

Adding some numbers for a base line. (Note all of these numbers are almost the upper limit of a well managed farm with very good cultivars)

Best yielding palms yield ~300 nuts per pals at 70 palms/acre.

at 750g a dehusked nut with 20% oil yield

You get ~2.3 tonnes oil/acre.

For reference an a321neo burns around 2,300 kg of fuel per hour when cruising
