During the feasibility study of a project, the initial estimated cost for design and construction is $3.7 million. It is anticipated that the cost to maintain and operate the facility after completion of construction will be $250,000 per year. Assuming the owner must obtain a return on the initial investment of 15%, what net annual income must be received to economically justify the project? Assume no salvage value after using the facility for 12 years.

Water is pumped from a reservoir to a tank with a lift of 20.0 ft. The suction pipe, which connects the reservoir to the pump, has a 12in diameter and is 25ft long. The discharge pipe, which connects the pump to the tank, has a 10in diameter and is 4..
In a particular fission event, a thermal neutron produces fission of a U-235 atom. For this particular event, the fission products Br-90 and Xe-143 are produced as well as 3 neutrons. How much energy in MeV is produced from this event?
Briefly discuss the operation and application of venturi meter, pitot tubes, electromagnetic and acoustic meters in fluid measurements
An insulated rigid tank is divided into two equal parts initially by a partition. Initially, one part contains 5 kg of air at 800 kPa and 75° C and the other part is evacuated. The partition is now removed and the air expands into the entire tank. De..
Is blue sky polarized, is the sun polarized? Blue light reflected from a glass table polarized? Why do some sunglasses block glare of off water and others do not? What other applications are there for polarizers?
Sketch the shear force and bending moment diagrams for the simply supported beams and cantilevers shown in Figures 1.87-1.91 . Indicate the magnitude and nature of the maximum shear force and bending moment and the positions where they occur.
you are handed an apple that has a mass of 102g. to get a better idea of what different pressures feel like you rig up
Consider a cold air-standard Diesel cycle. At the beginning of the compression process, the pressure is 0.1 MPa, the temperature is 320 K, and the volume of air is 0.02 m3. The maximum temperature of the cycle is 1500 K, and the compression ratio is ..
