generally used for this type of flow measurement are $lb\frac{s}{m}in$ or $k\frac{g}{m}in.$ Figure below illustrates an example of how a load cell measures the flow of solids. The equation that describes the flow $($Q$)$ is:

$Q=\frac{WV}{L}$

where:

$Q=$ the rate $of$ flow

$W=$ the mas$\frac{s}{w}$eight $of$ the solid

$V=$ the velocity$/$speed of the moving transporter

$L=$ the length of the weight transducer $($load cell$)$

$kg\frac{s}{m}in.$

Find the speed at which the conveyor must run to obtain the required flow. Also, suggest how to control the conveyor so that the flow rate remains constant.
