The time constant in the Kern-Seaton correlation for time dependence of the fouling resistance has the following physical meaning:

(a) time required for the fouling resistance to reach 50% of its asymptotic value

(b) time required for the fouling resistance to reach its asymptotic value

(c) time required for the fouling resistance to reach 63% of the asymptotic value

(d) time required for the fouling resistance to reach 99% of the asymptotic value
