Liquid dairy manure is applied with irrigation water or injected into the soil, as well as being used for the production of biogas. One of the problems facing dairy operations is the slurry manure transportation and pumping through pipelines to distant locations of the farm, especially when the sand content (used as bedding material) increases. In this study, rheological properties of sand-laden dairy manure (SLDM) including total solids (TS%), density and apparent viscosity were determined at four levels of manure solids (7, 10, 13 and 16 %TS) as well as the liquid manure taken from a manure separator tested at shear rates of 1.76 to 225.28 using a concentric cylindrical rheometer. Effect of temperature on the apparent viscosity at five levels (10, 21,... |

Biophysical properties of agricultural materials are important in designing of processing machines. In this study, some physical properties of tomato (Solanum lycopersicum) fruits were determined and their mutual relationships were studied. Dimensions (major diameter, minor diameter, and length), mass, volume, fresh and dry matter weight, as well as rupture point under uniaxial loading were measured. Other properties; including Poisson's ratio, modulus of elasticity, energy for rupture, density, arithmetic mean diameter, geometric mean diameter, diameter of equivalent volume sphere, and sphericity were calculated accordingly. Statistical analysis of the data indicated significant correlations between the rupture force and fresh weight, volume, dry weight,... |
