One side of a plate is heated with uniform flux while the other cc side exchanges heat by convection and radiation. The surface emissivity is H, heat transfer coefficient h, ambient temperature surroundings temperature T∞ plate thickness L1 and the conductivity is k. Assume one-dimensional steady state conduction and use a simplified radiation model. Determine: , Tf,sur
[a] The temperature distribution in the plate.
[b] The two surface temperatures for:
If you were developing a business continuity plan for your company, where would you start? What aspects of the business would the plan address?
Design a BJT differential pair amplifier (balanced in, unbalanced out) that provides 20 dB differential gain and 40 dB CMRR. Assume b = 100, ro = 50 KW. Use dual dc power supplies +Vcc and -Vee.
What is the impact of EMI on fiber optic cables?
Draw a relay wiring diagram for a circuit that implements the simple logic diagram shown in Figure 12.35. The circuit should be in the style of Figure 12.1(a).
Careful measurements in a certain non-magnetic (µ = µ0) medium reveal that the penetration depth of a 100 MHz uniform plane wave is 4 meters and the wavelength is p / 6 meters.
The propagation law follows the free space up to a distance ofdbreak = 50 meters, and for larger distances the receive power is similar to(d/dbreak)-4.2. Transmit antenna gain is -7dB; the receive antenna gain is 9 dB. Compute the available fadi..
A standard silicon NPN BJT is to be used as an amplifier. The emitter voltage is biased at 4 volts, the base is biased at 5 volts, and the collector is biased at 10 volts. Will this circuit perform as desired? Why or why not.
The direction of induced e.m.f. (and hence current) is given by Fleming's right hand rule. Therefore, the essential components of a generator are:
At time t = 0, the voltage across a 100-pF capacitor is -5 V. the current through the capacitor is 10[u(t) - u(t -10^-4)] μA. what is the voltage across the capacitor for t>0.
The power factor of a load connected to a 120-V 60-Hz source is raised from 0.866 lagging to 0.966 leading by connecting a 110.5-?F capacitor in parallel with the load. Determine the load current I1 and the circuit current IT.
Find the total impedance Zt, in rectangular and polar.- R1=2 ohms, R2=10 ohms Xc=6 ohms - (B) R1=1k ohm, R2=4k ohms,Xl1=3k ohms,Xl2=7k ohms.
Consider the circuit in figure 4-31 in your textbook. You have picked a test pattern set that is capable of 89% fault coverage. How many faults can your test pattern set detect (Assume the circuit is only susceptible to stuck-at-faults.)
