Total Time of Concentration Solution

Follow our step by step solution on how to calculate Total Time of Concentration?

FIRST Step Consider the formula

t c = T i + T m/f

Next Step Substitute values of Variables

∴

t c = 94.78min + 19.44min

Next Step Convert Units

∴

t c = 5686.8s + 1166.4s

Next Step Prepare to Evaluate

∴

t c = 5686.8 + 1166.4

Next Step Evaluate

∴

t c = 6853.2s

LAST Step Convert to Output's Unit

∴

t c = 114.22min

Variables

Time of Concentration

Time of Concentration is a concept used in hydrology to measure the response of a watershed to a rain event.

Symbol: t_c

Measurement: TimeUnit: min

Note: Value can be positive or negative.

Formulas to find Time of Concentration

Inlet Time

Inlet Time is the time taken by water to flow overland.

Symbol: T_i

Measurement: TimeUnit: min

Note: Value should be greater than 0.

Formulas to find Inlet Time

Channel Flow Time

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.

Symbol: T_m/f

Measurement: TimeUnit: min

Note: Value should be greater than 0.

Formulas to find Channel Flow Time

Other formulas in Channel Flow Time and Time of Concentration category

Go Channel Flow Time or Gutter Flow Time

T m/f = \frac{L}{V}

Go Length of Drain given Channel Flow Time

L = T m/f \cdot V

Go Velocity in Drain given Channel Flow Time

V = \frac{L}{T m/f}

Go Inlet Time or Time of Equilibrium

T i = {(0.885 \cdot (\frac{{(L ob)}^{3}}{H}))}^{0.385}

How to Evaluate Total Time of Concentration?

Total Time of Concentration evaluator uses Time of Concentration = Inlet Time+Channel Flow Time to evaluate 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 evaluate Total Time of Concentration using this online evaluator? To use this online evaluator for Total Time of Concentration, enter Inlet Time (T_i) & Channel Flow Time (T_m/f) and hit the calculate button.

FAQs on Total Time of Concentration

What is the formula to find Total Time of Concentration?

The formula of Total Time of Concentration is expressed as Time of Concentration = Inlet Time+Channel Flow Time. Here is an example- 1.606333 = 5686.8+1166.4.

How to calculate Total Time of Concentration?

With Inlet Time (T_i) & Channel Flow Time (T_m/f) we can find Total Time of Concentration using the formula - Time of Concentration = Inlet Time+Channel Flow Time.

Can the Total Time of Concentration be negative?

Yes, the Total Time of Concentration, measured in Time can be negative.

Which unit is used to measure Total Time of Concentration?

Total Time of Concentration is usually measured using the Minute[min] for Time. Second[min], Millisecond[min], Microsecond[min] are the few other units in which Total Time of Concentration can be measured.
