00:01
So in part a, in this solution, first we need to find the graph.
00:09
So we will draw the c value and percentage finer.
00:20
So let on x axis we have particle size in mm.
00:27
That is 4 .75 mm -m to 0 .5m.
00:59
250, 0 .10, all are in mm, and 0 .070.
01:31
Then on y -axis we have percentage finers, 10, 20, 30, 40, 50, 60, 60, 70, 80, 80, 90, 90, 90, 90, 90, 90 ,00.
02:05
This percentage finer and this is particle size in mm.
02:16
So we get the graph for 2 .5 it is 7 .75 it is when we are here.
02:44
It is the synthesis.
03:06
So this is the graph for the part a.
03:12
Then in part b, you need to find d10, d30 and d60.
03:14
So for the part a.
03:14
So for the part a, then in part b, we need to find d10, d30 and d60...
