A developer proposes to construct an apartment building near an existing retaining wall (Figure P7.27). The building of width 12 m and length 300 m (parallel to the retaining wall) will impose a surface stress of 150 kPa. In the preliminary design, the long edge of the building is located 1 m from the wall. Assume the building load can be treated as a strip load.
(a) Plot the distribution of the lateral force increase with depth up to a depth of 4 m.
(b) What is the maximum value of the lateral force increase, and where does it occur?
(c) If the embedment depth of the retaining wall is 4 m, calculate the maximum additional moment about the base of the wall (point O in Figure P7.27) from constructing the building.
(d) What advice would you give to the developer regarding how far the apartment should be located from the existing retaining wall?
Air enters an adiabatic nozzle at 4MPa and 400 K with a velocit of 25 m/s. Air at the exit is 2 MPa and a velocity of 160 m/s. Calculate entropy? Is this a reversable process?
