(a) 10 kN/m^3

(b) 9 kN/m^3

(c) 5 kN/m^3

(d) 2 kN/m^3

I had been asked this question in an interview for job.

Origin of the question is Classification of Fluids topic in chapter Fluid Flow and Mixing of Bioprocess Engineering

Answer 1

The correct choice is (b) 9 kN/m^3

For explanation I would say: Given data: Volume = 5 m^3

Weight = 45 kN
