A sheet pile wall has been installed partially through a silty sand layer. Assume the sheet pile is 12m long and penetrates 6m into the silty sand layer of thickness 12m. For this condition a) Draw the flow net using 3 (max 4) flow channels. The flow net should be completely symmetrical about the bottom of the sheet pile b) If the water height on the upstream side is 5m and on the downstream side 1m, compute the amount of water flowing under the sheet pile per meter of wall if the coefficient of permeability is 3.1x10-4 cm/sec. c) Compute the maximum hydraulic gradient at the downstream side of the sheet pile

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
