Design a single-column footing (including dowels) to support an 11 in. square column reinforced with eight no. 9 (no. 29) bars centered 2.5 in. from the column faces (equal number of bars on each face). the un-factored axial dead load 135 kips, and the un-factored axial live load 125 kips. for the column, fc= 4000 psi and fy= 60,000 psi. the base of the footing will be 3ft below grade. the allowable soil bearing pressure is 3000 lb/ft2. material strengths for the footing are pc= 3000 psi and fy= 60,000 psi.

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.
