We discuss the reverse sprinkler problem: How does a sprinkler turn when submerged and made to suck in water? We propose a solution that requires only a knowledge of mechanics and fluid dynamics at the introductory university level. We argue that as the flow of water starts, the sprinkler briefly experiences a torque that would make it turn toward the incoming water, while as the flow of water ceases it briefly experiences a torque in the opposite direction. No torque is expected when water is…

Sprinkler head revisited: momentum, forces, and flows in Machian propulsion
Many experimenters, starting with Ernst Mach in 1883, have reported that if a device alternately sucks in and then expels a surrounding fluid, it moves in the same direction as if it only expelled
New angles on the reverse sprinkler: Reconciling theory and experiment
The reverse sprinkler problem popularized in Richard Feynman's memoirs has long been a source of interest and controversy. Numerous theoretical and experimental studies have illuminated many
The puzzle of the steady-state rotation of a reverse sprinkler
The continuous rotation of the reverse sprinkler has been a puzzle for over two decades. This article presents a series of experiments that demonstrate that a properly designed reverse sprinkler
Aspirating cantilevers and reverse sprinklers
• Engineering
• 2009
The dynamics of a cantilevered pipe conveying fluid is discussed with a focus on the inverse problem, that is, when the pipe is aspirating rather than discharging fluid. The convoluted history of the
Irreversibility in an ideal fluid
When a real fluid is expelled quickly from a tube, it forms a jet separated from the surrounding fluid by a thin, turbulent layer. On the other hand, when the same fluid is sucked into the tube, it
The ‘acoustic scallop’: a bubble-powered actuator

The device described here consists of a millimeter-size tube immersed in a liquid, closed at one end, and partially filled with gas. A sound field in the liquid causes the gas volume to pulsate
Baroclinic Vortices in Rotating Stratified Shearing Flows: Cyclones, Anticyclones, and Zombie Vortices
Large coherent vortices are abundant in geophysical and astrophysical flows. They play significant roles in the Earth's oceans and atmosphere, the atmosphere of gas giants, such as Jupiter, and the
