Akubuo and Eje [5] among other things determined
the bulk density of unidentified mixture of varieties of
palm kernels. The method used was not mentioned
but a value of 568.90kg/m3 was computed for the kernels
at an average moisture content of 9.5% w.b.
Ekwulugo [6] determined the bulk density of dura
and tenera varieties of palm kernels. A 95mm diameter
cylindrical container of height 300mm was used
to measure the volume required for the investigation.
A result of 173.01kg/m3 was computed for dura and
164.67kg/m3
for tenera. The moisture content of the
sample used was not mentioned. Koya et al. [1] measured
the bulk density of dura (13.4% w.b.) and tenera
(12.1% w.b.) varieties by finding the ratio of the
mass of the samples to its total volume freely filling
a container without compaction. Results were 710.0
kg/m3 and 711.10 kg/m3
for dura and tenera varieties
respectively.
Ezeoha [4] used the above method by [1] and got a
value of 608.05kg/m3
for unidentified mixture of varieties
of palm kernels. The average moisture content of
the kernels was 10.7% w.b. The published values show
a discrepancy which is attributable to varied methodology,
equipment, and variety of sample.
