Introduction to Steel Design

The area of steel design is majorly concerned with the structural engineering domain, which is a specialization of civil engineering. Steel design is often known as structural steel design, whose primary concern is to design steel structures. The primary structure involves the designing and construction of frames using structural steel as the material. Residential buildings, houses, bridges, complexes, tall buildings, industrial warehouses, aircraft frames, frames of ships, and stadiums are some of the examples of structures that use steel framing.

Question

If the BOD4 of a waste is 135 mg/L and K is 0.075 day^-1, the 5-day BOD (BOD5) and ultimate BOD (BODu or L0) of this waste are nearly? Use equations K = (2.303)K relationship, if necessary.

1) BOD5= 157 mg/L; and BOD= 271 mg/L
2) BOD5 = 271 mg/L; and BOD₁= 157 mg/L
3) BOD5= 257 mg/L; and BOD=571 mg/L
4) BOD5= 357 mg/L; and BOD= 471 mg/L
