What are Culverts?

A culvert is a structure that allows water to flow under a road, railroad, trail, or similar obstruction from one side to the other. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material.

How to Calculate Velocity of Flow Fields?

Velocity of Flow Fields calculator uses Mean Velocity of Culverts = sqrt(Head Loss of Friction/((1-Entrance Loss Coefficient)/((2*[g]))+(((Manning’s Roughness Coefficient)^2)*Length of Culverts)/(2.21*Hydraulic Radius of Channel^1.33333))) to calculate the Mean Velocity of Culverts, The Velocity of Flow Fields formula is defined as rate at which water is flowing in the channel from head to tail. Mean Velocity of Culverts is denoted by v_m symbol.

How to calculate Velocity of Flow Fields using this online calculator? To use this online calculator for Velocity of Flow Fields, enter Head Loss of Friction (H_f), Entrance Loss Coefficient (K_e), Manning’s Roughness Coefficient (n), Length of Culverts (l) & Hydraulic Radius of Channel (r_h) and hit the calculate button. Here is how the Velocity of Flow Fields calculation can be explained with given input values -> 10.00028 = sqrt(0.8027/((1-0.85)/((2*[g]))+(((0.012)^2)*3)/(2.21*0.609^1.33333))).
