Aconsolidation test on a saturated clay soil gave the following results: cc = 0.2, cr = 0.04, and ocr = 4.5. the existing vertical effective stress in the field is 120psf. a building foundation will increase the vertical total stress at the center of the clay by 80psf. the thickness of the clay layer is 1.5â•›m and its water content is 36%. (a) calculate the primary consolidation settlement. (b) what would be the difference in settlement if ocr were 1.5 instead of 4.5?

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
