h = H_in-(K_e+1)*(v_m*v_m/(2*[g]))
This formula uses 1 Constants, 4 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Normal Depth of Flow - (Measured in Meter) - Normal Depth of Flow is a depth of flow in a channel or culvert when the slope of the water surface and channel bottom is the same and the water depth remains constant.
Total Head at Entrance of Flow - (Measured in Meter) - Total Head at Entrance of Flow is the measure of fluid's potential at the entrance.
Entrance Loss Coefficient - Entrance Loss Coefficient is defined as the amount of head lost at entrance.
Mean Velocity of Culverts - (Measured in Meter per Second) - Mean Velocity of Culverts is defined as the average velocity of a fluid at a point and over an arbitrary time T.

STEP 1: Convert Input(s) to Base Unit

Total Head at Entrance of Flow: 10.647 Meter --> 10.647 Meter No Conversion Required
Entrance Loss Coefficient: 0.85 --> No Conversion Required
Mean Velocity of Culverts: 10 Meter per Second --> 10 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h = H_in-(K_e+1)*(v_m*v_m/(2*[g])) --> 10.647-(0.85+1)*(10*10/(2*[g]))

Evaluating ... ...

h = 1.21462502995416

STEP 3: Convert Result to Output's Unit

1.21462502995416 Meter --> No Conversion Required

FINAL ANSWER

1.21462502995416 ≈ 1.214625 Meter <-- Normal Depth of Flow
