← ScienceWhich outcome reduces accuracy when using a pitot tube due to an increased Reynolds number?
A)Flow becomes fully turbulent
B)Higher viscosity reduces static pressure
C)Boundary layer detachment occurs✓
D)Fluid density significantly decreases
💡 Explanation
Increased Reynolds number promotes an unsteady and turbulent boundary layer. Boundary Layer Detachment causes inaccurate pressure readings, because the inertial forces become high therefore pressure distribution gets altered, rather than laminar sublayer maintaining smoother flow near the wall.
