A flow velocity field \(\vec V:\vec V(x, y)\) for a fluid is represented by
\(\vec V = 3\hat i+ (5x)\hat j\)
In the context of the fluid and the flow, which one of the following statements is CORRECT?

For assessing the compliance with the emissions standards of incineration plants, a correction needs to be applied to the measured concentrations of air pollutants. The emission standard (based on 11% Oxygen) for HCl is 50 mg/Nm³ and the measured concentrations of HCl and Oxygen in flue gas are 42 mg/Nm³ and 13%, respectively.
Assuming 21% Oxygen in air, the CORRECT statement is:
