The following correction should be made to “Flow Rate Measurement of Non-Newtonian Fluids through Sharp Crested Notches” by Morakane Khahledi, Rainer Haldenwang, and Raj Chhabra, https://doi.org/10.1061/(ASCE)HY.1943-7900.0000941:

Several equations in the original paper contain typographical errors. The corrected equations are provided herein and use the equation numbers listed within the original paper

Q = \frac{2}{3} b \sqrt{2 g} H^{3 / 2}

(2)

Q = \frac{2}{3} C_{d} b \sqrt{2 g} H^{3 / 2}

(3)

Q = \frac{2}{3} C_{d} \sqrt{2 g} (b + K_{b}) {(h + K_{h})}^{3 / 2}

(4)

Q = 2 \int_{0}^{H} \sqrt{2 g h} (H - h) \tan (\frac{θ}{2}) d h

(5)

Q = \frac{8}{15} C_{d} \tan (\frac{θ}{2}) \sqrt{2 g} H^{5 / 2}

(6)

{Re}_{3} = \frac{8 ρ V_{A N N}^{2}}{τ_{y} + K {[\frac{8 V_{A N N}}{D_{shear}}]}^{n}}

(13)

Notation

The following symbols are used in this paper:

$θ$: angle of V-notch.

The authors regret the errors.

To preserve the published version of record, these details have been corrected only in this erratum.
