A thermocouple has a time constant of 2 sec. A thermal well has a time constant of 30 sec. When the thermocouple is inserted into the well, this tempera turemeasuring device can be considered a two-capacitance systemDetermine the time constants of the combined thermocouple-thermal-well system Assume that the weight of the thermocouple is 8 g and the weight of the thermal well is 40g. Assume also that the specific heats of the thermocouple and thermal well are the same
A student lifts a weight (W) using a motor powered by solar cells to determine the efficiency of the solar cell/motor system. On the power meter the voltage reads V and the current reads I. The student lifts the weight a distance H in a time T.
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).
-What is Industrial Automation, Their Types and Hierarchy of an Industrial Automation System -Why Industrial Automation? (Advantages of Automation System)
a) At what time does the peak value of the AC signal occure b) What is the frequency,f,of the AC signal c) What is the period,T,of the AC signal d) At what time does the negitve peak value of the AC signal occur
The accompanying schematics each show two inductors with coupling but with different dot markings. For each of the two systems, determine the equivalent inductance of the system at terminals 1-1' by combining inductances.
you have the task of ordering a replacement inductor for one that has become defective. The information on the nameplate has been painted over and cannnot be read. The machine that contains the inductor on 480V at a frequency of 60 Hz.
Two point charges, and , are located at (1,2,0) and (2,0,0),respectively. Find the relation between and such that the total force on a testcharge at the point (-1,1,0) will have (a) no x-component, (y) no y-component.
The bandwidth of a series resonant circuit is 400 Hz. (a) If the resonant frequency is 4000 Hz, find Q. (b) If R = 10?, what is the value of XL at resonance (c) Find the inductance L and capacitance C of the circuit.
Given the following difference equation with the input-output relationship of a certain initially relaxed system (all initialconditions are zero), y(n) - 0.7 y(n-1) + 0.1y(n-2) = x(n) + x(n-1)
Draw the PLC ladder diagram for the circuit
What is the new resistance level of a copper wire if the length is changed from 200ft to 100yd, the area is changed from 40,000CM to 0.04 in.^2, and the original resistance was 800m ohms. CM stands for circular mill not cm^2.
To meet the signal-to-noise ratio of the receiver, the received power must be at least 10 µ W. Assuming the two antennas are aligned for maximum reception to each other, including being polarization matched, what should the gain (in dB) of the tra..
