Rc passive filters 1. design a single stage high pass filter that passes frequencies above 100hz and attenuates frequencies 2. design a single stage low pass filter that passes frequencies below 100hz and attenuates frequencies 3. what do you expect to happen to the cutoff frequency as more and more passive filtering stages are . how does cascading effect the bandwidth? below 100hz above 100hz cascaded?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
