“…Some other physical parameters were determined using the procedures described in the literature: equivalent diameter (D e ), mean diameter (D g ), sphericity (Ø), arithmetic mean diameter (D a ) and surface area (S) (Mohsenin, 1970;Mohsenin 1986), volume (V) by liquid displacement method (Aydın, 2002), volume (V) by calculation (Jain and Bal, 1997), aspect ratio (R a ) (Omobuwajo et al, 1999), bulk density (Parrott and Thrall, 1978), porosity (Nimkar and Chattopadhyay, 2001) and angle of repose (Bart-Plange and Baryeh, 2003).…”

41Physico-mechanical seed properties of the common Turkish bean (Phaseolus vulgaris) for 'Hinis' and 'Ispir', respectively. The average 1000 seed weight, bulk density, and porosity were determined as: 531.3 and 598.9 g, 835.8 and 872.7 kg m -3 , and 34.0% and 33.1% for 'Hinis' and 'Ispir', respectively. The average angle of repose and terminal velocity were 24.52° and 19.46°, and 11.42 and 11.80 m s -1 in 'Hinis' and 'Ispir' respectively. The highest coefficient of dynamic friction was obtained with an aluminium surface in both cultivars as 0.227 for 'Hinis' and 0.199 for 'Ispir'. This was followed by fibreglass, steel, plywood, and glass surfaces. Both cultivars had white testae. The average value of rupture force, deformation at rupture point, energy absorbed, hardness, and toughness along the

“…Furthermore, the shape indices indicated that the palm fruit and seed may be treated as a scalene ellipsoid for an analytical prediction of its postharvest processes. All the aspect ratios of fan palm fruit and seeds are found to be higher than those of African breadfruit (47.8), Chia seeds (62.7-65.2) and chickpea (75.6) and lower than bambaraa (84.6) (Ixtaina et al, 2008;Mpotokwane et al, 2008;Omobuwajo et al, 1999;Tabatabaeefar et al, 2003).…”

“…Low aspect ratio indicates the tendency to be oblong in shape (Omobuwajo et al, 1999). However, with an aspect ratio of over 70%, the palm fruits and seed are more likely to roll than to slide.…”

A b s t r a c t. In this study some physical properties of fan palm (Washingtonia robusta) fruits, seeds and seed coats were determined using dimensional, bulk and single kernel physical analysis. The moisture content of whole fruits, seeds and seed coats was 12.0, 9.86 and 13.87% (d.b.), respectively. The sphericity values showed that seed shape (0.86) is close to a sphere, similar as the fruit shape (0.83), both of which were close to a scalene ellipsoid shape. The surface area values of fruits and seeds were obtained as 163.27 and 80.25 mm 2 , and volume values were obtained as 190.96 and 66.32 mm 3 , respectively. Bulk densities of fruits, seeds and seed coats were 559, 783 and 272 kg m -3 , and the corresponding true densities were 1143, 1147 and 864 kg m -3 , whereas the corresponding porosities were 48.87, 54.12, and 31.52%, respectively. The values of the static coefficient of friction and the angle of repose of fruits, seeds and seed coats of palm fruits were studied on aluminium, canvas, galvanised iron, plywood, PP knitted bag, PVC and stainless steel surfaces. As expected, seed coat has higher values of coefficient of static friction on the all surfaces than fruit and seed.
