FILTERS
An electric filter is a network designed to attenuate certain frequencies but pass others without
attenuation. A filter circuit, therefore, possesses at least one pass band a band of frequencies in which
the output is approximately equal t

1. A bathtub is being filled with water, but the drain plug does not fit properly and water
leaks out. The volumetric flow rate of water down the drain is proportional to the
pressure drop across the plug according to V = 90(
Tutorial 5: Solutions
1.
Drag can be determined by summing the pressure forces.
Pf = Front pressure
Pr = Rear pressure
D = PfA - PrA
D = 0.7 (0.5v2A) (-0.4)(0.5v2A)
The pressure on the rear is in vacuum so it is negative.
D = 1.1(0.5v2A)
CD = D/(0.5v2A) =
