Question

A rectangular trough, 2.0 m long, 0.50 m wide, and 0.50 m deep, is completely full of water. One end of the trough has a small drain plug right at the bottom edge.
When you pull the plug, at what speed does water emerge from the hole? (in m/s)

Answer 1

V = sqrt (2 g H), where H is the height of the water level abouve the hole. The area of the trough does not matter.
