Chute Design Calculations

D is the chute diameter in meters m is the rocket mass in kilograms g is the acceleration of gravity = 9.8 m/s 2; p is 3.14159265359 r is the density of air = 1.22 kg/m 3; C d is the drag coefficient of the chute, which is 0.75 for a parasheet (flat sheet used for a parachute, like Estes rockets), or 1.5 for a parachute (true dome-shaped chute).

  • Transfer Chutes Design with Rocky DEM – SIMULATE …

    The angle at which the material hits the walls of the chute largely affects the wear. This angle will depend on the material velocity and properties of the material. Modification can be done to the chute design to minimize wear, such as by adding a curved guide surface at the mouth of the chute to direct the flow and make it smoother.
