Question

A liquid has a mass density of 1550 kg/m^3. Calculate its specific weight.

(a) 1.50×102 N/m^3

(b) 1.52×104 N/m^3

(c) 1.54×104 N/m^3

(d) 1.50×104 N/m^3

This question was posed to me in unit test.

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

Answer 1

Right option is (b) 1.52×104 N/m^3

To explain I would say: Given data: Mass density = 1550 kg/m^3

Specific weight = mass density × Acceleration due to gravity

= 1550 kg/m^3 × 9.8 m/s^2

= 1.52×10^4 N/m^3.
