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?
an amplifier with 40dB of small signal , open circuit voltage gain ,an input resistance of 1 Mega ohm , and an output resistance of 10 ohm , drives a load of100 ohm. What voltage amd power gain (expressed in dB) would u expect with the load connec..
state the probability distribution of the binomial random variable X. What is the probability that the random variable X falls in the interval [u - 3 sigma, u + 3 sigma]. The mean and the variance of a binomial distributin.
Hosts A and B are communicating over a TCP connection, and Host B has alreadyreceived from Host A all bytes up through (and including) byte 248. Suppose Host A then sends two back-to-back segments to Host B.
if a 2.000Å (.2nm) photon interacts with the bound electron in an hydrogen atom (binding energy 13.6 eV) with a Compton collision. The electron moves forward in the same direction as the incident photon. It may be convenient to use hc 12408eV
A phase modulation is used to transmit the signal s(t) = 10cos(20*pi*t) + 5sin(10*pi*t). kp = 3 rad/volts and fc = 20MHz a) What is the instantaneous frequency of the signal b) Write down the expression of the transmitted signal.
A class C amplifier severely distorts the signal. How can we use a resonant tuned filter to get the desired signal at the output What type of transistor (BJT or FET) would you like to use at the front end (first amplifier) of a receiver
A sequential circuit with two D flip flops, two inputs x and y, and one output z is specified by the following next state and output equations: A(t + 1) = xy + x'B B(t + 1) = y'A' + yB
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
Discuss different types of addressing modes of HCS12. What is a relative addressing mode What is the difference between a direct and an extended addressing mode Discuss how Registers X and Y are used in index addressing mode.
A CS amplifier using an NMOS with gm = 3.8 mA/V is found to have an overall voltage gain of -16 V/V. What value should a resistance RS inserted in the source lead have to reduce the overall voltage gain to -8 V/V
The fuel tank contains 33 kWh per gallon. If the vehicle were to be replaced by an electric vehicle that charges from the power grid, how much power would it draw (in W, kW, or MW) to recharge at the same rate as the gasoline powered automobile
moore sequential circuit has one input and one output, that creates a pulse when ever its input signal goes from 1 to 0 after this pulse a new pulse will not be given unless the input signal is again returned to 1 and then tranistion back to 0.
