The infiltration capacity of a soil follows the
Horton's exponential model f = C₁ + C₂ e-kt. During
an experiment, the intial infiltration capacity was
observed to be 200 mm/hr. After a long time the
infiltration capacity was reduced to 25 mm/h. If
the infiltration capacity after 1 hour was 90 mm/
h the value of the decay rate constant k (in h-¹,
up to two decimal places) is
