Variables Used

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.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Mean Velocity of Culverts: 10 Meter per Second --> 10 Meter per Second No Conversion Required
Manning’s Roughness Coefficient: 0.012 --> No Conversion Required
Length of Culverts: 3 Meter --> 3 Meter No Conversion Required
