A tank of 0.52 m3 capacity is filled with steam at 2 MPa and 350oC. The tank and its contents are slowly cooled to 125oC. Answer the following questions assuming that there was a negligible volume change during the cooling process:
(a) Show the process on a T-v diagram with respect to saturation lines. Label your sketch.
(b) What is the final quality of the mixture?
(c) What will be the final amounts of saturated vapor and saturated water?
A digital system is described by the following difference equation: y[n] = x[n] - 0.3 x[n-1] + 0.28 x[n-2] Find the transfer function H(z), the denominator polynomial A(z), and the numerator polynomial B(z).
To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided
A current density J¯ = ˆy sin(2x) A/m^2 is subject to a z-directed magnetic field H¯ = ˆz10 A/m. a. Assuming the vacuum permeability (i.e. a non-magnetic medium), what is the magnetic flux
A shunt regulator utilizing a zener diode is biased on through a 100 resistor. Determine the change in the regulated output voltage for the two situations below: a) VI changes +2.0 V, ILoad constant b) ILoad changes +100 mA, VI constan..
An engineer intends to study an input signal with frequency components of 5, 6, and 10 kHz. It is desired that all other frequencies be filtered out. A) What kind of filter does this require
Write a program to generate a 25-Hz digital waveform with a 50 percent duty cycle on the PT0 pin as long as the voltage level on the PP7 pin is high. Your program should consist of two parts: Entry test. As long as the PP7 pin is low, it stays in t..
A 30-km, 34.5-kV, 60-Hz three-phase line has a positive-sequence series impedance z = 0.19 + j0.34 ?/km. The load at the receiving end absorbs 10 MVA at 33 kV. Assuming a short line, calculate: (a) ABCD parameters,
The steering wheel has backlash. This means there is a delay between the time the wheel is turned, and the time the car responds. The driver tends to overturn, which leads to instability and lack of control of the car.
The load on a 460-V, 60-Hz, Y-connected, balance three-phase source consists of three equal Y-connected impedances of 100+j100 ohms, and three equal Delta-connected impedances of 300-j300 ohms. Compute the line current, power, and power factor for..
Consider an RLC circuit with R = 5 Ohms, L= ½ H, C= 2/9 F and input voltage e(t) = exp(-t/2)a. Starting from KVL show that the DE for the voltage across R is given by: v'' + 10 v' + 9 v = -5 exp(-0.5 t) b. Find vc in terms of the arbitrary constants ..
Using Multisim, design a mod-100 BCD counter that drives a 2-digit, 7-segment display. The count sequence will be 0 through 99. Blank leading zeros in the tens digit of the display.
Discuss the various ways to include conditional program flow control in 80x86 assembly programming. What are some limitations implementing this flow control when compared to higher level languages
