Calculation of parameter k<sub>1</<sub> by the Modified Lane method, Victor Miguel Ponce, San Diego State University

    online_modified_lane_k1: Calculation of parameter k₁ of the Modified Lane relation

Formula:

k₁ = Q_s / [ 58.7 γ Q_w S_o (R / d_s)^1/3 ]

SI Units (metric): Q_s in M.Tons/day, Q_w in m³/s, S_o in m/m, R in m, and d_s in mm.
U.S. Customary Units: Q_s in Tons/day, Q_w in ft³/s, S_o in ft/ft, R in ft, and d_s in mm.
