Dropping sand onto a conveyor belt | Physics Forums - The Fusion .Jan 30, 2012 . The problem statement, all variables and given/known data. Sand is placed onto a horizontal conveyor belt. rate of sand placed = 0.5 kg s-1 velocity of conveyor belt = 2 m s-1 a) what is the power supplied by the system to keep the velocity constant? b) what is the rate of change of KE by the sand c) why is.physics sand on conveyor belt pictures,physics sand on conveyor belt pictures,Physics HL/SL Help - Physics - IB SurvivalNah the question is asking: Sand is poured vertically on to a moving conveyor belt at a steady rate so that the mass of sand landing per unit time is m. The conveyor belt maintains a constant speed of v. The sand slips on the conveyor belt until it also reaches the speed v. [figure which I am too lazy to scan].

Solutions-Probem set #7The force allows the sand to be carried at a constant speed, even if the changing mass on top of the conveyor belt is increasing. Because of the conservation of the momentum, the rate of change in the momentum of the conveyor belt induced by the falling sand is also equal to the rate of change of the falling sand.physics sand on conveyor belt pictures,Sand Runs From A Hopper At A Constant Rate Dm/dt O. | Cheggsand runs from a hopper at a constant rate dm/dt onto a horizontal conveyor belt driven at a constant speed V by a motor. Find the power needed to drive the belt. Compare this with the rate of change of kinetic energy of the sand. Can you account for the difference?

Hosepipes, helicopters and conveyor belts. 1. Hosepipe. You can appreciate that if you are hit by a fast moving stream of water from a hose pipe you experience a force - if this hosepipe is a water cannon then the force could be great enough to knock you over. Consider a hosepipe of cross sectional area A that gives a jet of.

I find out the power supply by the force is twice that of the gain in kinetic energy of the sands. I cannot figure out where the other half of the power is dissipated ? ANSWER: Friction between the sand and the belt must exist. Another way of saying it is that the collision between the belt and the conveyer is not elastic. The lost.

### Mythbusters, airplane on a conveyor belt - Kottke

Jan 30, 2008 . Starting in about 40 minutes, I'll be liveblogging the Mythbusters episode where they take on the infamous airplane on a conveyor belt problem. . (For an explanation, try this one by my friend Mouser, who has a MIT Ph.D in Physics Sc.D. in Nuclear Science and Engineering.) . Hello picture-in-picture.

### Angle of repose - Wikipedia

The angle of repose is sometimes used in the design of equipment for the processing of particulate solids. For example, it may be used to design an appropriate hopper or silo to store the material, or to size a conveyor belt for transporting the material. It can also be used in determining whether or not a slope (of a stockpile,.

We have attached an image for reference. We appreciate any clarity you could provide :-) [Note that the angle relative to the horizontal is specified to be 600-700 in the photograph attached by the questioner.] ANSWER: My first reaction was to say that, of course, it would not hit the line. That was because, as physicists often.

### Crowned Pulleys. - Lock Haven University

Other belt-driven machinery revealed the same thing. Aha! Could this somehow be causing the belt to ride onto this elevated center section and stay there? But why would the belt prefer a larger diameter, and greater tension? It seemed counter-intuitive. But one thing I've learned in my years in physics is that one's naive.
