Kalgoorlie Konstruction is considering the purchase of a truck. Over its five-year life, it will provide net revenues of Si 5 000 per year, at an initial cost of $65 000 and a salvage value of $20 000. KK pays 35% in taxes and its after-tax MARR is 12%. What is the annual cost or worth of this purchase, given that KK uses a diminishing value rate to calculate depreciation?
a stream of methanol vapor is used to chill a countercurrently flowing saturated steam in an adiabatic heat exchanger.
the lowest temperature that has been achieved is about 1 times 10-6 k. to achieve this an additional stage of cooling
If the tank is filled to a depth of 3 0 ft with sea water, and the walkway is 8 ft above the fluid surface, how much force is required to remove the stopper?
Consider a 2 mm thick silicon wafer to doped using antimony (Sb). Assume that the dopant source (gas mixture of Antimony Chloride and other gases) provides a constant surface concentration of 6.4*10^22 atoms/m3. A heat treatment is desired such that ..
The actual part temperature is measured with a thermocouple which indicates 315?C. Both measurements have an uncertainty of ±1?C. From these measurements, determine the emissivity of the metal part and its uncertainty.
A vibrating spring-mass system has a measured acceleration amplitude of 8 mm/s2 and measured displacement amplitude of 2 mm. Calculate the system's natural frequency.
The worktable of a numerical control machine tool is driven by a closed-loop positioning system which consists of a servomotor, leadscrew, and optical encoder.
