  • How to Calculate the Angle of Repose Sciencing

    The angle of repose is the minimum angle at which any piled-up bulky or loose material will stand without falling downhill. One way to demonstrate this would be to pour sand from a bag to the ground. There is a minimum angle or maximum slope the sand will maintain due to the forces of gravity and the effect of friction between the particles of

    Tribological testing and analysis of metallurgical-grade cokes were conducted to elucidate the nature of the surface of each coke and the influence of the surface on coke abrasion resistance. The coefficient of friction (COF) was contrasted between cokes of different coal origins. The results indicate that the COF increases with (i) parent coal vitrinite content and (ii) decreasing rank of the
