1. Estimate the amount of Ca(OH)2(s) leached from concrete during a one-year period by precipitation. Assume that the area receives 40 in/yr of precipitation which is in equilibrium with PCO2= 10^-3.5 atm and [SO42-] = 10^-4 M. Assume that: a. The rain and concrete reach equilibrium rapidly. b. The remaining chemistry of the concrete does not impact leaching of Ca(OH)2(s). c. Within the concrete, assume a closed system with CT in solution equal to that in the incoming precipitation.
2. Assume that the primary driver for oxygen to rebar in concrete is rainwater. a. For the same climate conditions in problem 1, estimate the mass of rust formation for rebar during a year in concrete if the [O2] is 8 mg/L. Assume complete reaction. 2Fe + 3/2 O2= Fe2O3 b. Is this a reasonable estimate? Explain.

If the amount of heat transfer in the HE unit is 2460 kJ per kg of steam, what is the magnitude of shaft work obtained from the turbine in kW?
Solid waste will be applied in 0.6 m "lifts" and will be compacted to a depth of 0.3 m. Daily cover soil will be applied to a depth of 0.15 m for the first four days of the operation in any week. At the end of the fifth day, a "weekly cover" layer..
The shape below has a cut along the entire length of the member thus making it an open section. The uniform thickness is 0.125in. Determine the maximum shear stress for the shape. Compare the stress for this open shape to a shape without a cut.
