The flux rule of electromagnetic induction is an empirical formula,which is an approximation result of the theory of electronic circuits. Combining with the concepts of electromagnetic fields, it was used to derive the Faraday's law of induction in Maxwell equations, which is a fundamental law of...

The free volume theory proposed by Doolittle is protracted for a shear thickening fluid. An empirical formula is proposed to relate the shear viscosity of shear thickening fluid with a relative free volume of the fluid. The stresses generated in the fluid due to intermolecular forces, hydrodynamic...
