A six-cylinder, four-stroke, 4.5-L compression-ignition engine operates on the ideal diesel cycle with a compression ratio of 17. The air is at 95 kPa and 55°C at the beginning of the compression process and the engine speed is 2000 rpm. The engine uses light diesel fuel with a heating value of 42,500 kJ/kg, an air-fuel ratio of 24, and a combustion efficiency of 98 percent using constant specific heats at 850 K, determine (a) the maximum temperature in the cycle and the cutoff ratio (b) the net work output per cycle and the thermal efficiency, (c) the mean effective pressure, (d ) the net power output, and (e) the specific fuel consumption, in g/kWh, defined as the ratio of the mass of the fuel consumed to the net work produced.
A strain gauge has a GF=2.14 and a nominal resistance of 120 Ohm . Calculate the resistance change resulting from a strain of 144µin / in .
Use the MATLAB function file you created to create an echo signalusing your original speech signal and a constant attenuation. Youwill need to create a signal that is a scaled version of theoriginal and add it to the original with the desired offs..
A finite state machine has one input, X, and one output, Z. The output becomes 1 and remains 1 thereafter when, starting from reset, at least two 1s and one 0 have occurred as inputs, regardless of the order in which they appeared.
Find the capacitive susceptance per km of a single-phase line operating at 60Hz, using both the capacitance formula and the Tables. The conductor is Partridge, and spacing is 20ft between centres.
An equilateral glass prism w/ an index 1.42 has a beam of light incident on one face at an angle of θi to the normal. Determine the angle at which it emerges from an adjacent face of the prism.
In a steam plant where you work, the turbine develops 1000 kW. The heat supplied to the steam in the boiler is 2800 kJ/kg and the heat rejected by the steam to the cooling water in the condenser is 2100 kJ/kg.
You decide to use Holzer's method to find the natural frequencies of the system and determine the mode shapes, and to construct a plot of total torque vs. a, over the frequency range where the mode frequencies exist.
A charge of -1 nC is located at the oriogin in free space. What charge must be located at (2,0,0) to cause Ex to be zero at (3,1,1)
A piece of n-type silicon is doped so that the majority carrier concentration is 10^15 cm^-3 What is the minority carrier concentration? (ni = 1.5 x 10^10 cm^-3) If a piece of silicon is doped with phosphorus to 10^17 cm^-3, what are the equilibrium ..
An inverting amplifier is configured for a gain of -(6/4) using an opamp that has a 2mV internal offset voltage. (You may consider the opamp ideal otherwise). For what input voltage the output of the amplifier will be zero.
if the LM324 is a single supply Op Amp, how can it be used to amplify an AC signal that oscillates between a positive peak and a negative peak
If you measured a sinusoidal waveform on both the AC and DC scaleswith the same multimeter, and measured 1.5 volts AC scale and 1.0volts DC scale, what would be the maximum and minimum of the waveform displayed on the oscilloscope
