Laminar Flow in Helical Coils: A Parametric Study [Industrial & Engineering Chemistry Research 2011, 50, 1150–1157. DOI: 10.1021/ie101752z]. Ritu Gupta, R. K. Wanchoo, and T. R. M. Jafar Ali

The equation published on page 1152, near the top of the lefthand column, ( ) π2 ðDc =dt Þ NGn ¼ NRe  δ ¼ NRe  2 ½πðDc =dt Þ2 þ p=dt is incorrect. The above equation should be replaced by the equation given below: " #   π p=dt NGn ¼ NRe  τ ¼ NRe  2 ½πðDc =dt Þ2 þ p=dt
