HJ Heinz Corporation is constructing a distribution facilityin Italy for products such as Heinz Ketchup, Jack Daniel's Sauces,HP steak sauce, and Lea & Perrins Worcestershire sauce. A15-year life is expected for the structure. The exterior of thebuilding is not yet selected. One alternative is to use theconcrete walls as the facade. This will require painting now andevery 5 years at a cost of $80,000 each time. Another alternativeis an anodized metal exterior attached to the concrete wall. Thiswill cost $200,000 now and require only minimal maintenance of $500every 3 years. A metal exterior is more attractive and will have amarket value of an estimated $25,000 more than concrete 15 yearsfrom now. Assume painting (concrete) or maintenance (metal) will be performed in the last year of ownership to promote selling the property. Use future worth analysis and i = 12% per yearto select the exterior finish.
Lab studies have shown that the rate constant associated with the process are as follows: k = 0.95 mg COD/mg VSS-day; Y = 0.48 mg VSS/ mg COD, half-saturation K = 85 mg COD/L; ke = 0.07 d-1.
Compute the energy loss in a 90 degree bend in a steel tube used for a fluid power system. The tube has a 0.5 inch outside diameter and a wall thickness of 0.065 inches. The mean bend radius is 2.00 in. The flow rate of hydraulic oil is 3.5 gal/mi..
Explain CBR method of pavement design with one example.
What is the reaction that occurs with hexanal and propanol (give both the hemiacetal and acetal products)?
As the piston is compressed, the pressure also increases by 2000000 Pa. If there is 4 times as many atoms of nitrogen as helium, how many moles of helium are in the cylinder?
If the BOD5 of a municipal wastewater is 310 mg/L and the BOD U is 340 mg/L, determine the BOD reaction rate constant (base e). What would be the 3 day 30°C BOD Assume, temperature coefficient = 1.047.
A 1.0-m rigid horizontal support is hung by two cables. One cable is brass and The other cable is high-density polyethylene plastic. At room temperature (21°C), the cables measure 3.50 m vertically.
What is the final equilibrium temperature of the two bodies?
How long would it take to fill a 30 yd^3 packer truck that compresses waste to 750 lb/yd^3 if it travels 100 ft between stops at an average of 5mph and it takes 1 minute to load 200 lb of waste at each stop
A 2-inch by 2-inch solid steel beam (18 inches long) is fixed to the wall at the left to resist applied moment (20,000 lbs-inch). What would the deflection be at the right end Up or down
A gate valve is located at the end of the pipe. If the valve is closed suddenly, determine the maximum water hammer pressure that will develop in the pipeline. The water level in the reservoir is 98.4 ft above the outlet.
An overhanging beam ABC is subjected to a couple MA at the free end (see figure). The lengths of the overhang and the main span are a and L, respectively. Determine the angle of rotation and deflection at end A.
