Input interpretation
Hazen-Williams equation
Equation
v = 0.849 m^0.37/s C R^0.63 S^0.54 | v | flow velocity of fluid S | hydraulic grade line slope C | Hazen-Williams coefficient of roughness R | hydraulic radius (head loss due to friction)
Input values
hydraulic grade line slope | 0.00012 Hazen-Williams coefficient of roughness | 150 hydraulic radius | 15 meters
Result
flow velocity of fluid | 5.354 m/s (meters per second) = 11.98 mph (miles per hour) = 17.57 ft/s (feet per second) = 63239 ft/h (feet per hour) = 19.28 km/h (kilometers per hour) = 462.6 km/day (kilometers per day)
