Retardation Coefficient. The retardation coefficient expresses how much slower a contaminant moves than does the water itself. where R is the retardation coefficient, r b is the bulk density, k d is the sorption coefficient, and q is the porosity. Background. A simplified method of accounting for sorption is …

The following formula is used to determine the response factor: Response Factor (RF) = Peak Area. Concentration in mg/ml. Relative Response Factor (RRF)

R = Retardation factor 2018-06-25 The retardation factor (R) is one of the coefficients that de-scribe the migration abilities of particular components in groundwater. It shows how many times the migration of the substance subjected to adsorption slower than the actual speed of water flow in pores (Deutch, 1997). The retardation factor Originally Answered: How do I calculate the retardation of the body travelling with a velocity of 100 M per second which is brought to rest in 20 seconds? Retardation in general context means negative acceleration (deceleration). It (a) is expressed as delta v over delta t. a= the change in velocity divided by the change in time. 2005-07-19 Formula: a = (v - u 2)÷2s.

The equation to calculate the retardation factor of sorbing chemicals moving in aqueous solution through aquifers and vadose zones is derived using a linear sorption isotherm and a mass‐balance approach. The procedure is very simple and clearly illustrates the roles of porosity and water content,

Calculation: R = [1 + (p b /è) (K d )] R = [1 + { ( (1.75 g/cm 3 )/0.20) (3 mL/g) (1cm 3 /1mL)}] R = [1 + 26.25] R = 27.25. To calculate retardation use the standard formula V = U + at.
