A Note on the Static Hole Error Problem

The static hole error problem has been extensively investigated in the past. It has been shown that, for deep holes (for which the length l of the hole is greater than 1.5 times the diameter d of the hole), the difference between the indicated static pressure p0’ and the true static pressure p0 is a function of the boundary shear stress τ0, hole diameter d, the coefficient of dynamic viscosity μ and the mass density ρ of the fluid.
