Question
The drive roller for a conveyor belt is shown in Figure P6.11. Determine the linear speed of the belt when the roller operates at 30 rpm counterclockwise.
Step 1
The linear speed (v) of the belt can be calculated using the formula: \[ v = r \cdot \omega \] where \( r \) is the radius of the roller and \( \omega \) is the angular speed in radians per second. Show more…

Figure $P 5.58$ shows coal being dropped from a hopper onto a conveyor belt at a constant rate of $25 \mathrm{ft}^{3} / \mathrm{s}$. The coal has a specific gravity ranging from 1.12 to $1.50 .$ The balt has a speed of $5.0 \mathrm{ft} / \mathrm{s}$ and a loaded length of $15.0 \mathrm{ft}$. Estimate the torque required to turn the drive pulley of the conveyor belt. The drive pulley dianeter is $2.0 \mathrm{ft}$. Assume that there is no friction between the belt and the other rollers.
A belt is placed around a pulley that is $30.0 \mathrm{~cm}$ in diameter and rotating at $275 \mathrm{rpm} .$ Find the linear speed (in $\mathrm{m} / \mathrm{s}$ ) of the belt. (Assume no belt slippage on the pulley.)
