NOAA diagram illustrating the concept underlying time of concentration. This image shows the basic principle which leads to determination of the time of concentration. Much like a topographic map showing lines of equal elevation, a map with isolines can be constructed to show locations with the same travel time to the watershed outlet. In this ...
A Maucha diagram, or Maucha symbol, is a graphical representation of the major cations and anions in a chemical sample. R. Maucha [1] published the symbol in 1932. [2] Maucha ionic diagram. It is mainly used by biologists and chemists for quickly recognising samples by their chemical composition. [3] [4] The symbol is similar in concept to the ...
Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...
Not to be confused with lag time. Lag time the time interval from the maximum rainfall to the peak discharge. Time to peak time interval from the start of rainfall to the peak discharge. Time of concentration Time of concentration is the time from the end of the precipitation period to the end of the quick–response runoff in the hydrograph. [3]
C Ao is the inlet concentration of species A; C A is the reactor/outlet concentration of species A; Residence time is the total amount of time a discrete quantity of reagent spends inside the reactor. For an ideal reactor, the theoretical residence time, , is always equal to the reactor volume divided by the fluid flow rate. [2]

Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move from a region of high concentration to a region of low ...
