The change from laminar flow to turbulent flow, in the case of water flowing through sand, occurs over a wide transition zone beginning with a Reynolds number of about 10. A method for estimating the exponent of the velocity term for head loss calculations involving flow into wells is presented. Typical calculations show that head losses due to aquifer turbulence may have been over-estimated in previously published material.
