A calibrated RTD with α = 0.0041 /?, R = 306.5 Ω at 20?, and P_D = 30 mW/? will be used to measure a critical reaction temperature. Temperature must be measured between 50° and 100? with a resolution of at least 0.1?. Devise a signal-conditioning system that will provide an appropriate digital output to a computer. Specify the requirements on the ADC and appropriate analog signal conditioning to interface to your ADC.
Calculate the probability that the system will fail in 3,000 hours. Supposing no failure of any component occurs in 5,000 hours of operation. What would be your revised estimate of failure rates of the components in your system?
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
A new government law requires that the lead content of drinking water be less than 1.0 ppb. You are a safety engineer, and you have recently tested your companys drinking water using two methods. Method A gives a reading of 0.85 ppb
For computer chip of 10mm (length), 5 mm(width) is operated by power of 0.645 watt, which surrounded by coolant material of temp of 80 F. Find the Surface Temperature in K of the computer chip during the heat transfer of convection.
An ordinary broadcast television channel has a bandwidth of 6 MHz. How many FM radio stations (with a bandwidth of 200 kHz each) could be accommodated in one television channel using FDM
Design a state variable two-pole band-pass filter with a geometric center frequency of 2KHz and a 3dB bandwidth of 20 Hz and the tuning resistances need to be 10Kohms each.
Once a week a wagon driver leaves his hut and drives his wagon to the river dock to pick up supplies for his town. At 4:05 PM, one-fifth of the way to the dock, he passes the Temple. At 4:15 PM, one-third of the way, he passes the Preetam-Da-Dhaba..
Three single-phase transformers rated at 15kVA, 480V/120V,60Hz are connected in delta to function as autotransformers on a 600V,3-phase line. The H1,H2,X1,X2 polarity marks appear on the metal housing.
A machine produces photo detectors in pairs. Tests show that the first photo detector is acceptable with probability 3/5. When the first photo detector is acceptable, the second photo detector is acceptable with probability 4/5.
if the energy strored in the fully charged battery is used to lift the battery with 100% efficiency, what height is attained. Assume that the acceleration due to gravity is 9.8 m/s^(2) and is constant with height.
a) Given that the refractive index of water is about 1.33, what is the polarization angle for light traveling in air and reflected from the surface of water b) Consider a diver in sea pointing a flashlight towards the surface of the water.
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,
