Given: C-50 Multiple Box Roller and DW-21 Tractor, Speed of Towing Tractor = 4.5 mph, P = 4 passes, W= 9.83 ft. C-50 Rolling Width, D = 12 in. depth of lift, F = 80% factor for common earth, E = 83% average efficiency, Estimating volume of compaction, [latex]V_{C}[/latex].

Accepted Answer

[latex]V_{C}=\frac{4.5 imes 5280}{4 imes 27} imes \frac{9.83 imes 12 imes 0.80 imes 0.83}{12} =1435 yd^{3} /hr\left(1096 m^{3} /hr ight)[/latex]
