Flow behavior index water
There are a number of other models that better describe the entire flow behaviour of shear-dependent fluids, but they do so at the expense of simplicity, so the power law is still used to describe fluid behaviour, permit mathematical predictions, and correlate experimental data. See more In continuum mechanics, a power-law fluid, or the Ostwald–de Waele relationship, is a type of generalized Newtonian fluid (time-independent non-Newtonian fluid) for which the shear stress, τ, is given by See more Dilatant, or shear-thickening fluids increase in apparent viscosity at higher shear rates. They are in … See more Just like a Newtonian fluid in a circular pipe gives a quadratic velocity profile (see Hagen–Poiseuille equation), a power-law fluid will result in a power-law velocity profile, where u(r) is the … See more Pseudoplastic, or shear-thinning are those fluids whose behaviour is time independent and which have a lower apparent viscosity at higher shear rates, and are usually See more A Newtonian fluid is a power-law fluid with a behaviour index of 1, where the shear stress is directly proportional to the shear rate: See more • Power law • Rheology • Navier–Stokes equations See more WebK = Consistency index, lb.s n /100 ft 2. n = Flow behavior index. and t and l subscripts indicate turbulent and laminar flow conditions respectively. ...
