Show the parameters of the primary fixed points defining the international Temperature scale of 1990-ITS90.
That is, m = 36 kg/h, with all other conditions the same. The thermo physical properties of the hot fluid are p = 1079 kg/m3, cp = 2637 J/kg · K, µ = 0.0034 N · s/m2, and k = 0.261 W/m · K.
Design an AC source system that can be used to power 120 Vrms, 240 Vrms, and 208 Vrms single phase devices depending upon the particular connection terminals. The system should have no individual sources with voltages larger than 120 Vrms.
Determine the maximum power that a 430 km, high-voltage 3-phase transmission line can transmit if the system voltage is 550kV and the impedance of the line is 0.5 ohm/km. Determine illuminance at a distance of 12 ft from source.
Design an Aritmentic unit that meets the following specifications. Two 32-bit operands as inputs 2-bit command as input to specify four operations ADD, SUB, MUL, DIV
A one quarter wavelength piece of 75 ohm microstrip line has a capacity load of Xc = 22 ohms. What impedance does a driving generator see
A solar pond consists of a thin layer of fresh water floating ontop of a denser later of salt water. When the salty layer absorbssun light, it becomes hot, to 140 degrees C. The ambient temp isassumed to be 20 degrees C.
(a) How long does the electron take to travel this 1.50 cm? (b) What is its acceleration?
An engineer intends to study an input signal with frequency components of 5, 6, and 10 kHz. It is desired that all other frequencies be filtered out. A) What kind of filter does this require
Calculate the series and parallel resonant frequencies of the crystal. - The magnitude and phase of the overall electrical impedance of the crystal at the above frequencies.
find the reactive vars which the compensation equipment must supply to maintain the voltage profile (a)when the line supplies load of 50 Mva at 0.85 p.f lagging (B) when the line is open circuited at the recieving end.
Determine the bandwidth of the modulator output if a power ratio, Pr, of 0.8 is needed. Repeat for a power ratio of 0.9.
A glass tube with a cross-sectional area of 9^-2 m^2 contains an ionizd gas. The densities are 10^15 positive ions/m^ and 10^11 free electrons/m^3. Under the influence of an applied voltage, the postive ions are moving.
