A steam power plant employs a closed feedwater heater to improved the thermal efficiency. Draw a chematic and T-S diagram for the cycle, and labe it. Write an expression for the thermal efficienc of the ecycle in accordance with the labelling. Also write the energy balance equation for the feedwater heter using the lalabeling on the diagram.
A full adder is a circuit which adds three bits X, Y, Z together and returns two bits C and S to represent the total as a 2-bit binary number C S. C is the MSB and S is the LSB. For example, if X=1, Y=1, Z=0, the total should be 2, or 102 in binar..
Use the concept of phasor to combine each of the following sinusoidal functions into a single trigonometric expression: (a) y = 50cos(500t + 60) + 100cos( 500t - 30) (b) y = 200 cos( 377t + 60) -100sin( 377t + 150)
The unknown input impedance of a horn antenna operated at a frequency of 300MHz is measured using a slotted transmission line and a Smith Chart. When the antenna is connected to the slotted line, the VSWR on the line is measured to be 4
how do we determine the direction of current in a multiloop circuit with more than one source of e.m.f?
At the receiver, demodulate the double side band signal S(t) = [cos(90*pi*t) + cos(120*pi*t)] * [cos(400*pi*t)], with the local carrier cos(400*pi*t). Design a low pass filter to suppress the carrier and plot the amplitude spectrum of S(t)
Identify the bus types and the unknown variables of the power flow problem. Write the complete set of equations needed to solve the load flow problem.
Derive the two-term including source match error correction formula. Note: For all of these derivations, you should identify your standards {match, short, open} but DO NOT assume anything about their values.
antialiasing and anti-imaging active filter Sampling rectangular pulses (sampling clock) set as the following. Vp (pulse value) = -5 volts, Period: 0.125 ms, Pulse width 0.02 ms Sinusoidal voltage source set as the following: Frequency = 1000 Hz , Vp..
A museum has three rooms, each with a motion sensor (m0, m1, m2) that outputs 1 when motion is detected. At night, the only person in the museum is one security guard who walks from room to room.
Using MatLab, create and graph the pairwise convolution of the following functions (i.e., A must be convolved with B, C, D, and E, individually. B must be convolved with C, D, and E, individually, Etc.). All time scales are -4 to +4.
Consider a disk that is scheduled using the Shortest Seek First (SSF) policy. At time t, let the disk have the following requests in its queue: Request Cylinder R1 45 R2 39 R3 49 R4 52 R5 69 R6 35 R7 3 R8 66.
Consider the collision between two hockey pucks in the figure below. They do not stick together. Their speeds before the collision are v1i = 26 m/s and v2i = 11 m/s. It is found that after the collision one of the pucks is moving along x with a sp..
