Answer:
5.0 cm/s
Explanation:
Q = V * A
given that the diameter of the particle = 0.1 cm
V = stream velocity , A = cross sectional area of stream , Q = stream flow
For a particle with a diameter of 0.1 cm,
To determine the stream velocity we will use a stadia rod to measure at least 5 meters down ( depth of stream ) three times and then take the average value which will be used to determine the cross sectional area of the stream but Given that the width of the stream is not given the closet value to the stream velocity will be = 5.0 cm/s
