← ScienceWhile calibrating a venturi meter in a pipeline, which consequence develops from underestimated fluid viscosity within the Bernoulli equation?
A)Overestimation of flow rate readings✓
B)Underestimation of pressure drop expected
C)Unexplained meter instability develops suddenly
D)Increased measurement noise significantly appears
💡 Explanation
Underestimated viscosity leads to an underestimated friction term in the energy balance, causing the calculated pressure difference to suggest a higher flow rate. Because the assumed flow rate is higher, therefore it overestimates the true flow, rather than showing pressure decreases.
