👉 Turbidimetrically refers to a measurement technique that uses the properties of water to determine the velocity or density of a fluid. This method involves using a device called a turbidity meter, which measures the amount of light reflected by particles in a liquid, such as water, and converts this information into a measure of the concentration of impurities in the liquid. The term "turbidimetrically" is derived from the Greek word "tubere", meaning "to reflect,"
