A project is being considered, benefits and costs are: Initial cost = $100,000. Additional cost at the end of year 1 = $50,000. Benefit at the end of year 1 = $0. Annual benefits at the end of Years 2-10 = $20,000. Interest Rate = 7%. Conventionally B/C ratio and whether the project is economically stable.
What is the definition of a customer? What are some examples of internal and external customers? Is the measurement of customer satisfaction different for internal customers than for external customers?
mechanical oscillations can be described in general by the following function: y(t)= e^(-t/m) *sin(wt+phi). where (t) is time and (w) is the oscillation angular frequency in radians per unit time.
Find the dimensions of a rectangular concrete channel to carry a flow of 150 m3/s, with bottom slope 0.015, and mean velocity 10.2 m/s.
Using darcy-weisbach equation, calculate the major friction head loss for a 24 inch diameter, 120 ft long pipe that can carry water with a flow rate of 5 cfs. Assume the temperature of water is 70 deg F and the roughness of the pipe is 0.0016 ft.
The tape is stretched over three equal spans. Calculate the tape corrections under the following conditions at field, temperature = 85ºF, pull = 18kg, E= 2.109 x 10 6 kg/cm 2
An underground limestone mine with production of 12,000 tons/day will use trucks for the main haulage between an ore pass and a hoist skip pocket. The hauling distance is 5500 ft. The main haulage drift is horizontal and is 12.5 ft wide and 12.5 f..
The acceleration of point A is defined by the relation a = -1.08sin kt - 1.44 cos kt, where a and t are expressed in m/s^2 and seconds, respectively, and k = 3 rad/s. knowing that x = 0.16 m and v = 0.36 m/s when t = 0
