15 صفحه اولComparison of One-point and Two-point Methods for Estimation of Infiltration Parameters in Furrow Irrigation
Infiltration is one of the most important hydraulic parameters affecting surface irrigation and one ofthe most difficult parameters in practical field determinations. The infiltration equations are used todescribe water flow hydraulics and surface irrigation systems design. But determination of theparameters in these equations are costly and time consuming. Therefore, some estimating methods ar...
متن کاملFlory-Huggins theory for athermal mixtures of hard spheres and larger flexible polymers.
A simple analytic theory for mixtures of hard spheres and larger polymers with excluded volume interactions is developed. The mixture is shown to exhibit extensive immiscibility. For large polymers with strong excluded volume interactions, the density of monomers at the critical point for demixing decreases as one over the square root of the length of the polymer, while the density of spheres t...
متن کاملPressure dependence of the Flory-Huggins interaction parameter in binary polymer blends investigated by SANS
The pressure dependence of the Flory Huggins interaction parameter of two binary polymer blends was investigated by small angle neutron scattering (SANS). We studied the polymer blends deutero PoIystyrene / Polyvinylmethylether (d PS / PVME) and deutero Polystyrene / Polyphenylmethylsiloxane (d PS / PPMS), exhibiting decomposition at high and at low temperatures, respectiveIy. In both cases the...
متن کاملMixing Plate-Like and Rod-Like Molecules With Solvent: A Test of Flory-Huggins Lattice Statistics
Boehm and Martire have shown that the Flory-Huggins (FH) lattice model applied to mixtures of squares and rigid rods in solvent on a two dimensional lattice gives different results depending on whether rods or squares are placed first onto the lattice. This correct derivation places the validity of the FH model itself into question since the final result should be independent of the order of pl...
