A Barnes and Books is interested in purchasing a two-story building for a new

retail store. They plan to use the first floor as the display/sales area and the

second floor for storage of inventory. Before buying the property, they have sked

you to verify the building will be safe for the intended use. You must determine if

the interior columns will carry a load of 32 kips (32,000 lbs.), the columns rest on

spread footings which are 4'-0" X 6'-0" X 1'-6" thick. Note the column load does

not include the weight of the footing. If the footing rests on silty sand can the

Does footing safely carry the column load?

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
