Maximum Escape Velocity - The Ofy

v = Final velocity. • R=retardation factor in [M/L3/ M/L3]= [Mobile chemical] +[sorbed chemical]/ [Mobile chemical] =1 + sorbed concentration/mobile concentration • So the rate at which the center of mass of a sorbing chemical moves through the aquifer is equal to; • v/R where v is the seepage velocity “Retardation factor”, R d 2 2 d H d x C R D x C R u t C ∂ ∂ + ∂ ∂ =− ∂ ∂ Substituting Equation 7 into Equation 6: (8) (7) Effect of adsorption to solids is an apparent slowing of transport of dissolved contaminants Both u and D H are slowed The following is an example calculation for the retardation coefficient. Given: K d = 3 mL/g (newsletter Vol. 8 No. 5 will cover details about the distribution coefficient) p b = 1.75 g/cm3. è = 0.20. 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. Since V is lesser than U , the answer you get will be negative and hence “a “will be retardation.

retardation. • The retardation ∆ may be calculated as follows. If t S is the time in seconds that it takes the slow ray to traverse the crystal and t F is the time it takes the fast ray to traverse the crystal, then the distance ∆ that the fast ray travels beyond the crystal before the slow ray emerges is ∆ = c (t S - t F) {units: m = (m/s)(s)}, Formula: R = Q mb ÷ TQ s.

incorporated into the transport model through the use of the retardation factor as defined in equation (2.6). Three types of equilibrium-controlled sorption  The following formula is used to determine the response factor: Response Factor (RF) = Peak Area. Concentration in mg/ml. Relative Response Factor (RRF)  at different speeds, causing them to separate; A retardation factor can then be calculated (Rf value = distance component travels ÷ distance solvent travels). The equation shows how the retention factor is influenced by flow rate (F), gradient time (tG), gradient range (DF), and column volume (VM).

Motsatsen till acceleration är retardation, om bilen minskar sin hastighet retarderar den således. Acceleration är kort och gott hastighetsförändring under ett visst tidsintervall.
