NOTE: Additional considerations when sizing vibrator to bins. 1. If bin side angle is below 30º, select next larger vibrator. 2. If bin thickness is extra heavy (see table under section B), select next larger vibrator. 3. On real sticky and hard to move materials, it is better to use two (2) small vibrators instead of a large one

Chute Sizing Calculations. Utilizing the formula for area of a chute and the area of a circle, the parachutes sizes were calculated. Based on the rocket parameters and desired terminal velocities: For 50 ft/s - Drogue = 30 inches in Diameter. For 20 ft/s - Main = 8 feet in Diameter. Parachutes will be annular. Increased performance/weight ratio ...

Head pulley diameter and face width help determine the width and height of the head chute. The space between the chutewall and the pulley rim should be small enough that large lumps are not able to pass from the carrying side to the return and are not caught between the pulley and the chutewall. A typical space is 50 to 75 millimeters (2 to 3 ...

A second section (chapter III) is devoted to the sizing and designs, i.e. how to size and where to place the various infrastructures of a gravity fed system. Calculation exercises are given at the end of the module (paragraph III.7) in order to put into practice the theory developed in this module (exercise corrections are given in appendix).
