1. The stream function for an incompressible, two dimensional flow field is
For this flow field, sketch several streamlines.
2. A line vortex of strength K at (x, y) = (0, a) is combined with opposite strength vortex at (0, a): Plot the streamline pattern and find the velocity that each vortex induces on the other vortex.
determine the order of the Butterworth low pass filter required to make the percentage of aliasing level at the cutoff frequency less than 10%.
The resistance, inductance, and capacitance in a parallel RLC circuit are 2000 Ohms, 250 mH, and 10 nF, respectively. a) calculate the roots of the characteristic equation that describe the voltage response of the circuit.b) Will the response be over..
A signal contains a mixture 30 , 100 and 240 Hz Sine waves and also contains wideband noise whose spectrum is from 500 Hz up to a 1000 Hz. Describe a filtering technique that can be used to cleanly separate 30, 100 and 240 Hz from each other and a..
