Question $4$

At $0630$ hours, $30kg$ of tracer was introduced into a stream. Samples were taken at half hourly intervals at two downstream stations and the data given below was obtained.

a$)$ Determine the streamflow at each of the two downstream stations.

b$)$ What are the probable reasons for the discrepancy between the streamflows computed at the two stations?

c$)$ Determine the mean velocity of the dye cloud between the two measuring stations.
