Discounted payback: Roswell Energy Company is installing new equipment at a cost of $10 million. Expected cash flows from this project over the next five years will be $1,045,000, $2,550,000, $4,125,000, $6,326,750, and $7,000,000. The company's discount rate for such projects is 14 percent. What is the project's discounted payback period?
A solid metal cube has a spherical cavity at its center as shown in Fig. 22-28. At the center of the cavity there is a point charge Q = +8.00 µC. The metal cube carries a net charge q = -6.00 µC (not including Q).
a certain 11 v dry-cell battery completely discharged requires a current of 100 ma for 1.2 hr to completely recharge.
What kind of a semiconductor is widely in integrated circuit electronics?
a) Plot the spectrum and the normalized spectrum of x[nT] = 2cos(20*pi*n*T + pi/8) + 4cos(40*pi*n*T + pi/8) for T = 0.01 b) Plot the spectrum and the normalized spectrum of
The input signal to a filter contains components that range in frequency from 100 Hz to 50 kHz. We wish to reduce the amplitude of the 50-kHz component by a fctor of 200 by passing the signal through a first-order lowpass filter.
The results of open-circuit and short-circuit tests on asingle-phase, 25kVA 440V / 220V, 60Hz transformer are as follows: Open-circuit test (primary open-circuited, with instrumentation on the secondary side): 220V, 9.6A, 710W.
Where f is a constant called the rolling resistance coefficient and W is the vehi- cle weight. For a vehicle weighing, W = 300 kN that is traveling at 100 km/h, calculate the power in kW required to overcome the vehicle rolling resistance for f ..
What is the difference between natural selection and ecological succession?
an interesting emerging market is using internet phone and a companys high speed lan to replace the same companys
When the motor runs at 1710 rpm, the line currentdrawn from the supply is 78 A at 0.85 PF lagging. Given that,stator iron loss is 2kW, windage and friction losses are 1.2kW andresistance between two stator terminals = 0.4W
