View solution

Q. Which of the flowing is true about two-parameter model?

View solution

Q. Statement 1: Apparent viscosity μ_a is related to shear stress (τ) and shear strain (γ) as μ_a= τ/γ.
Statement 2: The equation τ=Kγⁿ becomes μ_a= τ/γ = Kγ⁽ⁿ⁻¹⁾ .

View solution

Q. Statement 1: In μ_a= τ/γ = Kγ⁽ⁿ⁻¹⁾ , n = consistency index and K is the flow behaviour index.
Statement 2: n= 1 for Newtonian fluids, n<1 for dilatant fluids and n>1 for pseudo plastic fluids.

View solution

Q. Statement 1: Considering the equation, μ_a= τ/γ = Kγ⁽ⁿ⁻¹⁾ , for pseudo plastic fluids, n<1 and they’re called Shear thinning liquids and dilatant fluids are called Shear thickening liquids as n>1.
Statement 2: Cooked starch solution is a Shear thinning liquid and dairy cream is a Shear thickening liquid.
