Question

The expression of relative stability at 37^oC is given by ___________

(a) S = (1-(0.794)^T37)

(b) S = 100 (1-(0.794)^T37)

(c) S = 1-(0.794)^T20

(d) S = 100 (1-(0.630)^T37)

This question was addressed to me in my homework.

Question is from Population Equivalent and Relative Stability in section Wastewater Characteristics of Environmental Engineering

Answer 1

Right answer is (d) S = 100 (1-(0.630)^T37)

The best explanation: The expression of relative stability at 37^oC is given by

S = 100 (1-(0.630)^T37)  where T37 represents the incubation period at 37^oC.
