Answer»

The correct CHOICE is (d) In measuring WATER velocity

The best I can explain: The current velocity meter allows you to measure stream flow velocity in feet or meters PER second and measure water depth in hundredths of a foot up to three feet. The AVERAGE stream flow velocity times the cross-sectional AREA of the stream determines the stream flow measurement in cubic feet or meters per second.
