Abstract (2. Language): 
Angle of internal friction (0) and pressure ratio (k) are the most important in the design of storage systems of granular crops in point of distribution of pressure at the cross-section of silo. In the research, the angel of internal friction and pressure ratios of selected some granular crops -hazelnut, corn, barley, soybean-were evaluated as a function of moisture content of grain. In the study, the pressure ratio was determined according to three different methods. The research results showed that the angle of internal friction linearly increased with the increase in the grain moisture content for selected granular crops. The pressure ratios of hazelnut varied with the increase in the grain moisture content depend on variety. Also the pressure ratios of corn, barley and soybean linearly decreased with the increase in the grain moisture content at the every three methods. In respect to the statistical, effect of the moisture content of grain and method on pressure ratio is significant (P<0.01). Also the interaction of the moisture content *method is insignificant.

Abstract (Original Language): 
Taneli ürünleri depolama sistemlerinin projelendirilmesinde içsel sürtünme açısı (0) ve basınç oranı (k) depo kesit geometrisindeki basınç dağılımı üzerinde oldukça önemlidir. Bu çalışmada içsel sürtünme açısı ve basınç oranı tane nem kapsamının bir fonksiyonu olarak seçilmiş bazı taneli ürünler (fındık, mısır, arpa ve soya) için araştırılmıştır. Çalışmada basınç oranının belirlenmesinde üç farklı yöntem kullanılmıştır. Araştırma sonucunda tane nem içeriğindeki artışa bağlı olarak seçilmiş ürünlerde içsel sürtünme açısı pozitif lineer bir artış göstermiştir. Basınç oranı ise fındıkta çeşide bağlı olarak tane nem içeriğinin artışı ile değişkenlik göstermiştir. Mısır, arpa ve soyada ise tane nem içeriğinin artışına bağlı olarak basınç oranı her üç yöntemde de lineer olarak azalmıştır. Yapılan istatistik analiz sonucunda nem içeriği ve yöntemlerin P<0.01 olasılık düzeyinde basınç oranlarına önemli bir etkisinin olduğu, nem*yöntem interaksiyonunun ise önemsiz olduğu saptanmıştır.
