Victoria Falls

Victoria Falls (or Mosi-oa-Tunga, “the smoke that thunders”) is the world’s tallest waterfall. In the dry season it has a minimum volume rate of flow of 300 \(m^3/s\), and splits into 5 waterfalls along its 1708 \(m\) length. The highest of these is called Rainbow Falls, standing 108 \(m\) tall.

Question Text

If 70.9 \(m^3/s\) of water flows over Rainbow falls, by the time it reaches the bottom of Rainbow Falls, what cross-sectional area does this water have? (Please make the likely unreasonable assumptions that none of the water evapourates, and that it stays together as its area decreases).

Answer Section

Please enter in a numeric value in \(m^2\).
