Problem M. 385. (March 2019)

M. 385. When a relatively large obstacle having a horizontal (planar) face is placed under the water stream flowing from the kitchen tap, then the spreading water forms a circular area where it has a visible increase in its height. This is called the hydraulic jump. At a certain obstacle-tap distance, measure how the radius of the circle depends on the rate of water flow.
