Appendix B. Friction coefficient equation for Sarkar model

Three set of straight line equations are used for approximately model the variation of friction coefficient in the running in region. Straight line equations 21, 22, & 23 as shown below are modeled for the ranges of sling distance 0 to 60 m, 60 to 100 m & 100 to 120 m respectively. =      ×+0.1 (21) =    ×    (22) =       ×+0.5 (23) References A.J.
