Consider a river with a cross-sectional area of flow equal to 100 square metres and a flow velocity of 2 metres per second.What is this river's discharge?
A) 50 cubic metres per second
B) 100 cubic metres per second
C) 200 cubic metres per second
D) 400 cubic metres per second
E) There is not enough information given to determine the discharge.

Quizplus · Accepted Answer

Discharge is defined as the volume of water passing through a given cross-sectional area per unit time. It is calculated as the product of cross-sectional area and velocity. Therefore, discharge = cross-sectional area x velocity = 100m² x 2m/s = 200 cubic metres per second. The correct answer is option C).
