Data by A. T. Lenz for water at 208C (reported in Ref. 23) show a signifi cant increase
Chapter 10, Problem p10.119(choose chapter or problem)
Data by A. T. Lenz for water at 208C (reported in Ref. 23) show a signifi cant increase of discharge coeffi cient of V-notch weirs (Fig. P10.118) at low heads. For 5 208, some measured values are as follows: H, ft 0.2 0.4 0.6 0.8 1.0 Cd 0.499 0.470 0.461 0.456 0.452 Determine if these data can be correlated with the Reynolds and Weber numbers vis--vis Eq. (10.61). If not, suggest another correlation.
