Consider a semi-circular section of a tube with inside radius and outside radius Heat is exchanged by convection along the inside and outside cylindrical surfaces.
The inside temperature and heat transfer coefficient are and The outside temperature and heat transfer coefficient are and The two plane surfaces are maintained at uniform temperature. Write the two-dimensional steady state heat equation and boundary conditions.
What would be the initial value of v c (t) when switch is closed and determine the time constants in both cases (switch is open, switch is closed).
Describe how you would use the combination of a short pass filter, a long pass filter, an amplifier and a mechanicalchopper to amplify a 5 mV signal to a 50 mV signal and remove noisefrom the original 5 mV signal.
Rebuilt ignition systems leave an aircraft rework facility at the rate of three per hour on the average. The assembly line needs four ignition systems in the next hour. What is the probability that they will be available?
A filter with a great deal of attenuation must be placed in an amplifier chain. Ignoring all considerations other than the desire to minimize noise figure, would it be preferable to put the filter before or after a low noise amplifier Why
What is the resistance of a copper wire 200 ft long and 0.01 in. in diameter (T = 20°C)?
Design and simulate a power supply that takes line voltage and produces a 15V output with less than .5% ripple voltage.
For the networks of given figure, determine the current I2 using branch-current analysis, and then find the voltage Vab.
A high-pass filter is shown in Fig. 2.7a. If the cutoff frequency is to be 400 Hz,
assuming k>0 what is steady state the response of the above system due to an input of the form , x(t) = 2sigma(t)+u(t). where sigma(t) denotes unit impulse function and u(t) denotes unit step function
