PROBLEM 4: Consider a concrete retaining wall which the data of its height 5,4 m and
thickness 1 m. The backfill behind the wall will be from
local sandy gravel with a dry unit weight 18,01 kN/m3, cohesion = 0 , and internal
friction angle (28,47o) . The wall will not have to retain water.
Estimate, (a) the lateral force on the wall from the backfill in an active
pressure condition, (b) its stability against overturning, and (c) its stability
against sliding (use a Factor of Safety 2)

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
