A man owns a land that includes a low head water fall and wants to build a small hydroelectric plant. The effective head of the reservoir is 20 m. He used a tube of 3 m length and 1 m diameter as a penstock. He computed the speed of the water inside the penstock by dropping a small ball at the entrance of the tube and measuring the time it took to reach the other end of the tube. The ball traveled the penstock in 2 s.
a. Compute the power at the outtake of the tube.
b. If the coefficient of performance of the turbine is 0.95, and the efficiency of the generator turbine and generator is 90%, compute the expected generation of the site.
c. If the cost of building the small hydroelectric system is $10 M, compute the payback period if the cost of electricity from the neighboring utilities is $0.2/kWh. Assume that the water flow is always constant.
d. Is building this small hydroelectric system a good investment?
An enhancement-type NMOS transistor with Vt=2 V has its source grounded and a 3-V DC source connected to the gate. Determine the operating state if a. vd = 0.5 V b. vd = 1 V c. vd = 5 V
a sequential circuit has one input (X) and one output (F). The circuit examines groups of four consecutive inputs and produces an output F=1 if the input sequence 0101 or 1001 occurs. The circuit resets after every four inputs.
use MATLAB to compute state transition matrix and then obtain the step responses y1(t) and y2(t), given that the initial state vector is zero
Bob enters a pizza shop and notices there are three different sizes of pizzas available. Sizes are given as the diameter of the pizza in inches. The cost of a pizza is based on the size. Bob would like to know which size of pizza
Translate the following fragment of high-level language into 68000 assembly language. Assume the labels T, 'X', and er have already been defined as references to specific memory addresses.
Consider a PCM-TDM system in which 24 signals are to be processed. Each signal has a baseband bandwidth of 3 KHz. The sampling rate has to be 33.3% higher than the theoretical minimum, and 8 bits are to be used.
Consider the common-emitter amplifier shown in Figure. Draw the small signal equivalent circuit by assuming that the coupling capacitors are short circuits.
A circuit that is made from a voltage source in series with the switch then in series with the parallel set of a resistor and a capacitor. The switch is originally open, it is then closed.
Can one use a TV remote by reflecting the signal through a mirror?
A resistor on a Wheatstone bridge is replaced with a strain gage which has a nominal resistance of 120 Ohms and a gage factor of 2.06. The remaining resistors on this quarter-bridge Wheatstone bridge circuit are 120 Ohm fixed resistors.
Calculate the value of the energy stored when a current of 50 mA is flowing in a coil of inductance 200 mH. What value of current would double the energy stored?
Consider an analog periodic sinusoid x(t) = cos (3*pi*t + pi/4) being sampled using a sampling period Ts to obtain the discrete time signal x[n] = x(t)I t=nTs = cos (3*pi*t + pi/4). a.) Determine the discrete frequency of x[n].
