Design an active bandpass filter subject to the following constraints:

•cascade a first-order active lowpass filter, a first-order active highpass filter and possibly aninverting amplifier.
•fc1= 300hz and fc2= 3khz.
•maximum gain (gain at f0) in the passband 1 shall be 20db
•using standard resistor values available in the lab room.
•draw the schematic diagram of your finished design.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa. s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
