Sentence examples for time of concentration from inspiring English sources

Time of concentration (min).

Site time of concentration = 15 min.

As mentioned previously, in the SCS method, the minimum storm duration is 6 h unless the time of concentration of a basin becomes more than 6 h, where the minimum storm duration is considered equal to the time of concentration.

(2) where, V stormwater runoff volume, C runoff coefficient, I rainfall intensity, A catchment area, tc time of concentration.

We applied six different methods for estimation of time of concentration, another important design specification and took the arithmetic mean value of all methods.

Since the time of concentration of the studied basin is 4.5 h (less than 6 h), the continuity of storm was considered as 6 h.

In this paper, the comparison on the overland time-of-concentration shows that the average velocity-based time-of-concentration is longer than the maximum velocity-based time-of-concentration which is generally longer than the average celerity-based time-of-concentration for four flow regimes from laminar to turbulent.

Traditionally, the overland time-of-concentration and the time-of-travel in channel are estimated based on the flow velocity.

Based on the above, a drainage design which uses the average velocity to estimate the time-of-concentration and the time-of-travel produces smallest design discharge (i.e. least conservative design).

Despite the perception that a design which uses the maximum velocity to estimate the time-of-concentration and the time-of-travel produces a conservative design, this comparison shows that this is not the case when compared to another design which uses the average wave celerity.

Figure 3 shows the evolution over time of concentrations in eight surface and intermediate ocean basins attributed to various sources.
