Q2.

Environmental Engineering: A wastewater sample diluted 1:50 has initial dissolved oxygen $DO_i = 9.0\text{ mg/L}$ and 5-day dissolved oxygen $DO_f = 3.0\text{ mg/L}$ in 'Structural Analysis: Statically Determinate and Indeterminate Trusses, Arches, Moment Distribution'. The $BOD_5$ is:

(A)

$300\text{ mg/L}$ ($BOD_5 = (9.0 - 3.0) \times 50 = 6.0 \times 50$) (Structural Analysis: Statically Determinate and Indeterminate Trusses, Arches, Moment Distribution)

(B)

$150\text{{ mg/L}}$

(C)

$450\text{{ mg/L}}$

(D)

$60\text{{ mg/L}}$
