Difference between ball screw critical speed and characteristic speed

WebFeb 28, 2024 · As for the evacuation times and the walking speed, it is concluded that walking speed affects the evacuation time while the physical characteristics affect the flow rate through doors. Some interesting results were shown for the traveler and mixed groups. Although the flow rate was the same, the evacuation times show a 200 s difference. WebSince characteristic speed can be represented as length per unit time, , we get , where, m = mass, U = characteristic speed, L = characteristic length. Dividing both sides by , we get ⇒ , where, m = mass, U = characteristic speed, F = net external forces, L = characteristic length.
