A. Plot the pole‐zero pattern b. Write system’s I/O equations for A, B, and C when output is y and input is u. c. Determine ,  n , and K for B and C, and and Kfor A. d. Find the unit step response for A, B, and the unit impulse response for C using inverse Laplace transform. e. Use the final value theorem to determine the steady state response for A, B, and C for a unit step response.

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

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
