Total Time of Concentration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time of Concentration = Inlet Time+Channel Flow Time
t_c = T_i+T_m/f
This formula uses 3 Variables

Variables Used

Time of Concentration - (Measured in Second) - Time of Concentration is a concept used in hydrology to measure the response of a watershed to a rain event.
Inlet Time - (Measured in Second) - Inlet Time is the time taken by water to flow overland.
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.

STEP 1: Convert Input(s) to Base Unit

Inlet Time: 94.78 Minute --> 5686.8 Second (Check conversion here)
Channel Flow Time: 19.44 Minute --> 1166.4 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_c = T_i+T_m/f --> 5686.8+1166.4

Evaluating ... ...

t_c = 6853.2

STEP 3: Convert Result to Output's Unit

6853.2 Second -->114.22 Minute (Check conversion here)

FINAL ANSWER

114.22 Minute <-- Time of Concentration

(Calculation completed in 00.004 seconds)

What is Time of Concentration ?

Time of Concentration is a concept used in hydrology to measure the response of a watershed to a rain event. It is defined as the time needed for water to flow from the most remote point in a watershed to the watershed outlet. It is a function of the topography, geology, and land use within the watershed.

How to Calculate Total Time of Concentration?

Total Time of Concentration calculator uses Time of Concentration = Inlet Time+Channel Flow Time to calculate the Time of Concentration, The Total Time of Concentration formula is defined as the time required for water to travel from the most distant point in a watershed to the point of interest, typically where flow is measured or where a drainage system discharges. Time of Concentration is denoted by t_c symbol.

How to calculate Total Time of Concentration using this online calculator? To use this online calculator for Total Time of Concentration, enter Inlet Time (T_i) & Channel Flow Time (T_m/f) and hit the calculate button. Here is how the Total Time of Concentration calculation can be explained with given input values -> 1.606333 = 5686.8+1166.4.

FAQ

What is Total Time of Concentration?

The Total Time of Concentration formula is defined as the time required for water to travel from the most distant point in a watershed to the point of interest, typically where flow is measured or where a drainage system discharges and is represented as t_c = T_i+T_m/f or Time of Concentration = Inlet Time+Channel Flow Time. Inlet Time is the time taken by water to flow overland & 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.

How to calculate Total Time of Concentration?

The Total Time of Concentration formula is defined as the time required for water to travel from the most distant point in a watershed to the point of interest, typically where flow is measured or where a drainage system discharges is calculated using Time of Concentration = Inlet Time+Channel Flow Time. To calculate Total Time of Concentration, you need Inlet Time (T_i) & Channel Flow Time (T_m/f). With our tool, you need to enter the respective value for Inlet Time & Channel Flow Time and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
