can someone explain mathmatically the fluid mechanics of upside down dog water bowls?
7. A dog watches as a human places 4 cups upside down in a row on a table. The human places a dog treat under one of the cups as the dog watches, and then the human quickly rearranges the cups. The dog then chooses one of the cups; if the chosen cup has the treat underneath it, the dog gets the treat. (In case the setup for this problem is unclear - and also just for fun - here's...

A graduated cylinder filled with water rests upside down in a container of water at 0 C. The water is 7.00 cm deep. Attached to the base of the cylinder is a small ring (but since the cylinder is upside down, the ring is at the highest elevation, available for grabbing). The base of the cylinder has mass 10.0 grams with ring included. The cylinder itself has radius 3.00 cm, height 40.0 cm, and mass 100.0 grams (including the base...
Hi, i hope someone can help me with fluid mechanics questions Thanks! A buoy with a square cross-section of 1x1 cm has a length of 3m. The buoy is hinged at the top at point o, located 1 m above the water surface, and is fastened to the bottom of a reservoir with a cable. The buoy is made of a material with a uniform density of 700 kg/m3 Determine: a) the angle 0 the buoy makes with the horizontal...
In a 3-min or less recorded video, explain the purpose/use of Navier-Stokes equations in fluid mechanics. How are the equations used and applied? Give a detailed description of a specific use or application of the Navier-Stokes equation in water resources engineering. In what circumstances can you obtain an exact solution? Upload your video to Warpwire video in Isidore.
Explain in words why we need to introduce the stress tensor for fluid mechanics.
Fluid Mechanics. Please answer as many as you can. Short answer questions 1) Explain the physical meaning of the acceleration term uVu, where u is the velocity vector in a fluid. 2) Name the two equations that are required to describe the flow of an inertial jet in an incompressible, unstratified fluid. 3) What is the “Continuum Hypothesis”? 4) Describe how a viscous boundary layer adjacent to a solid surface results in transfer of momentum to/from that surface. 5) What...

If the pressure difference between the two tanks is 20kPa, calculate the values of a in centimeters (cm) and ? in degrees Note: ?Water 9.81 kN/m3. Water CI 26.8 cm 2a Water Mercury SG 13.6
1,Pour water into a soda can, fill a quarter of it with water. 2,Boil the water in the can on a hot plate. 3, Immerse can upside down into cold water. Make sure the top of the can is fully immersed in water so that gas in the can is sealed by the cold water. 4, Observe what happens to the can. the can crushes 4, Use ideal gas law to explain what happens.
Mechanical Engineering - Fluid Mechanics (Do Not convert to S.I. units) A jet of water issuing from a stationary nozzle with a speed of 20 ft/s strikes a turning vane mounted on a cart as shown. The vane turns the jet through an angle of 115 degrees. Determine the mass, m, required to hold the cart stationary. The jet diameter is 1.0 inch.
