Sentence examples for time of concentrations from inspiring English sources

For genetic regulatory networks described by graphs with a large number of vertices, and a complex structure of edges, the rate equations describing the evolution in time of concentrations are in general difficult to build, and are critically dependent on the assumptions done about the biological and the chemical interactions involved.

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

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).

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.

According to Table 4, the time for hydrograph peak discharge calculated using HEC-1 is 3 h, which is less than the time of concentration for the watershed.

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