Channel Flow Time or Gutter Flow Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Channel Flow Time = Length of Drain/Velocity in Drain
T_m/f = L/V
This formula uses 3 Variables

Variables Used

Channel Flow Time - (Measured in Second) - Channel Flow Time is the time taken for water to travel from the most distant point in a watershed to a specific outlet or point of interest within a channel or drainage system.
Length of Drain - (Measured in Meter) - Length of Drain refers to the total distance from the point where water enters the drainage system to the point where it exits or discharges into a larger water body or another drainage system.
Velocity in Drain - (Measured in Meter per Second) - Velocity in Drain is the speed of the water flowing through the drain.

STEP 1: Convert Input(s) to Base Unit

Length of Drain: 3.5 Kilometer --> 3500 Meter (Check conversion here)
Velocity in Drain: 3 Meter per Second --> 3 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_m/f = L/V --> 3500/3

Evaluating ... ...

T_m/f = 1166.66666666667

STEP 3: Convert Result to Output's Unit

1166.66666666667 Second -->19.4444444444444 Minute (Check conversion here)

FINAL ANSWER

19.4444444444444 ≈ 19.44444 Minute <-- Channel Flow Time

(Calculation completed in 00.004 seconds)
