Which consequence results when a Venturi meter is misapplied with non-Newtonian fluids?

A)Pressure drop accurately indicates flow
B)Turbulent flow becomes fully laminar
C)Shear-thinning affects viscosity measures
D)Viscosity causes minimal measurement impact

💡 Explanation

Spurious readings occur due to changing fluid properties. The assumed constant viscosity within Bernoulli’s equation no longer applies. Therefore, shear-thinning will introduce errors in the measurement, rather than an accurate measurement being obtained from the meter because viscosity affects pressure variations rather than flow alone.
