Suppose that volume transport of an ocean current is 50 x 10^6 m^3/s. Assume that this volume transport is carried in a current of uniform speed which is 50 km wide and 1 km thick. What is the average velocity of the current? Suppose that the velocity of a current is 0.2 m/s. Assume that the width and thickness of the current are 50 km and 0.5 km respectively. What is the volume transport associated with this current, in m^3/s?
