STEP 1: Convert Input(s) to Base Unit

William Hazen Coefficient: 119.91 --> No Conversion Required
Hydraulic Mean Depth: 10 Meter --> 10 Meter No Conversion Required
Bed Slope of Channel: 0.001 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_wh = 0.85*C_H*(m)^(0.63)*(s)^(0.54) --> 0.85*119.91*(10)^(0.63)*(0.001)^(0.54)

Evaluating ... ...

V_wh = 10.4297603298727

STEP 3: Convert Result to Output's Unit

10.4297603298727 Meter per Second --> No Conversion Required

FINAL ANSWER

10.4297603298727 ≈ 10.42976 Meter per Second <-- Flow Velocity for William Hazen's Formula
