1. What is cost levelizing and what is its importance?
2. What is depreciation and what is its impact in economic calculations?
3. Define the life-cycle cost and explain how life-cycle cost analysis is performed.
4. What is life-cycle savings and what is the difference between life-cycle cost and life-cycle savings with regard to the manner in which the economic analysis is performed?
Thin slot revisited. Repeat Problem 7.10, but include a second-order Mur boundary on each of the walls. Compare the fields leaking through the hole to the simulation without boundary conditions; how do they compare?
Two magnetically-coupled coils are wrapped around a mutualnon-magnetic material. The coefficient of coupling betweenthe coils is 0.388. L1 has 500 turns and a value of 23.75mH while L2 has700 turns and a value of13.70mH.
A 1 lb weight is suspended from a 0.005 in diameter wire. The unstrained resistance of the wire, R0, is 270 ohm, and its unstrained length is L0=36 in. The wire's gauge factor is 3.2. a. Calculate the psi tensile stress on the loaded wire.
An AM broadcast receiver's pre-selector has a total effective Q of 90 to a received signal at 1180 kHz and uses an IF of 455 kHz. Calculate the image frequency and its dB of suppression.
Two ammeters are put in parallel, and used to measure an unknown current. The unknown current is determined by adding the readings of the two ammeters. Ammeter #1 can read a maximum current of 50[A], and has a meter resistance of 2.35ohms.
Explain the differences between the engineering specifications you would write for a transducer to measure the frequency of an audible sound wave and a transducer to measure the frequency of a visible light wave.
Why should the number of inverters be odd? What could happen if an even number of inverters were used in the ring oscillator?
Given that, stator iron loss is 2kW, windage and friction losses are 1.2kW and resistance between two stator terminals = 0.4W, for slip s=0.05, mechanical power supplied to the load PL=41.5 kW and Motorefficiency h =82%; Calculate: Line current dra..
The discussion must address phase angle relationships of current and voltage. The answer must include the effect of source frequency on the voltage drolps across the resistor and the inductor at very loave and very high frequency values.
A heat engine with water as the working fluid operates with a thermal efficiency of 26%. The water enters the isobaric boiler as a saturated liquid at 3 MPa. If the work per kilogram of water is 710 kJ/kg determine the temperature of the boiler ou..
An infinitely long cylindrical dielectric of radius b contains charge within its volume of density ρv=aρ^2, where a is a constant. Find the electric field strength, E, both inside and outside the cylinder.
Suppose your multimeter is fused for 300 mA. You want to measure current through a resistor via a 9-volt battery. What is the minimum resistance such that the current is less than 150 mA
