1. An ideal gas with Cp/Cv=1.5 where Cp and Cv are respectively the heat capacities at constant pressure and constant volume, is used as the working substance of a Carnot engine. The temp of the source is 600K and that of the sink is 300K.
The volume of gas changes from 4 to 1 liter at the low temp and the pressure at the volume of 4 liters is one atm.
calculate the volumes and pressures at the extreme points of the high temp expansion.
calculate the heat absorbed there
Calculate the heat given out at the low temp
what is the efficiency ?
2. Two identical bodies of constant heat capacity are initially at temperatures T1 and T2. They are used as the sink and source of a Carnot engine and no other source of heat is available.
Calculate the final, common temperature when all possible work has been extracted from the system.
Calculate the maximum work obtainable.
Suppose we have a resistive load that varies from 5 kOhms to 10 kOhms. We connect this load to an amplifier, and we need the voltage across the load to vary by less than 1 percent with variations in the load resistance.
Design an analog computer circuit (using minimum resistor values of 10 k ohms ) to obtain the summing (adder) function. Vo = -v1 -v2 +v3
register windows each have 6 input registers and 6 output registers. how many local registers are in each register
given a triangular plane in the coordinate plane slanted with a surface bounded by the closed path. how to find the magnetic flux in that plane
Fundamentals of Electric Circuits fourth edition: alexander, sadiku chapter 12 problem 12.29 A balanced three phase wye-delta system has Van= 120 angle 0 Vrms and Zdelta= 51+ j45 ohms. if the line impedance per phase is 0.4 + j1.2 ohms,
A circuit is needed to display a 4-bit value on the LED's of a logic designer. This value can come from two differentsources. Design a circuit using four 2-to-1 muxes to select which of the two values to display on the LEDs.
Design an FSM that realizes a three-bit Gray-code counter, which counts in the sequence 000, 001, 011, 010, 110, 111, 101, 100, 000
Draw a timing waveform for the clock, input D, and outputs Qpos, Qneg, and Qms that illustrates the differences in input/output behavior of a positive edge-triggered D flip-flop, negative edge-triggered D flip-flop, and master/slave flip-flop.
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
Submit an excel spreadsheet with your characterization results, and a screen shot of you amplifier schematics, and your simulation result running a sin wave (Use a vsin for input).
Sketch and explain the interface of PPI 82C55A to the 8086 microprocessor in minimum mode.Interface 8 LEDs to the port B of 82C55A. Interface 8 keys to theport A. Assume that port A of 82C55A is located in the I/O memoryspace at FF0H.
A 4.0MΩ resistor is connected in series with a 5.0μF capacitor. The capacitor is initially uncharged. The RC combination is charged by a 9.0 volt battery. a. What is the change in voltage between t=RC and t=3RC
