Flow behavior index water

Webbehavior, different flow models are commonly used. One of the most frequently used is the Ostwald-de-Waele model, better known as the power-law model given by: τ=kγ n (1) where (Pa) is the shear stress, γ (s-1) is the shear rate, k (Pa.sn) is the flow consistency factor index and n (-) is the flow behavior index. 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. ...
