Length of Culvert given Velocity of Flow Fields Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Culverts = (Head Loss of Friction-(1-Entrance Loss Coefficient)*(Mean Velocity of Culverts*Mean Velocity of Culverts/(2*[g])))/((((Mean Velocity of Culverts*Manning’s Roughness Coefficient)^2))/(2.21*Hydraulic Radius of Channel^1.33333))
l = (H_f-(1-K_e)*(v_m*v_m/(2*[g])))/((((v_m*n)^2))/(2.21*r_h^1.33333))
This formula uses 1 Constants, 6 Variables

Constants Used

Variables Used

Length of Culverts - (Measured in Meter) - Length of Culverts is the measurement or extent of culverts from end to end.
Head Loss of Friction - (Measured in Meter) - Head Loss of Friction is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system.
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.
Manning’s Roughness Coefficient - Manning’s Roughness Coefficient represents the roughness or friction applied to the flow by the channel.
Hydraulic Radius of Channel - (Measured in Meter) - Hydraulic Radius of Channel is the ratio of the cross-sectional area of a channel or pipe in which a fluid is flowing to the wet perimeter of the conduit.

STEP 1: Convert Input(s) to Base Unit

Head Loss of Friction: 0.8027 Meter --> 0.8027 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
Manning’s Roughness Coefficient: 0.012 --> No Conversion Required
Hydraulic Radius of Channel: 0.609 Meter --> 0.609 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

l = (H_f-(1-K_e)*(v_m*v_m/(2*[g])))/((((v_m*n)^2))/(2.21*r_h^1.33333)) --> (0.8027-(1-0.85)*(10*10/(2*[g])))/((((10*0.012)^2))/(2.21*0.609^1.33333))

Evaluating ... ...

l = 3.00358465911657

STEP 3: Convert Result to Output's Unit

3.00358465911657 Meter --> No Conversion Required

FINAL ANSWER

3.00358465911657 ≈ 3.003585 Meter <-- Length of Culverts
