The forces Qy=12 kNQy=12kN and Qz=16 kNQz=16kN act on the profile at the shear center C. Calculate:
a) Shear flow at point B (2 points)b) Shear stress at point D (3 points)
Consider the feedback controlled blending system shown below, which is designed to keep theoutlet concentration constant despite potential variations in the stream 1 composition. The density of all streamsis 920 kg/m3. At the nominal steady state, the flow rates of streams 1 and 2 are 950 and 425 kg/min,respectively, the liquid level in the tank is 1.3 m, the incoming mass fractions are x1 = 0.27, x2 = 0.54. Noticethe overflow line, indicating that the liquid level remains constant (i.e. any change in total inlet flow ratetranslates immediately to the same change in the outlet flow rate). You may assume the stream 1 flowrate andthe stream 2 composition are both constant. Use minutes as the time unit throughout this problem.
d) Derive the first order process and disturbance transfer functions;Gp= Kp/(tou*s+1) and Gd=Kd/(tou*s+1) and calculate and list the values and units of the parameters.

a) Briefly explain what ratio control is. Give an example of a common chemical engineering situation in whichratio control would be useful and for that example state exactly how ratio control works (what would bemeasured, what is set, and how the controller logic works).b) Briefly explain what cascade control is. Give an example of a common chemical engineering situation inwhich cascade control would be useful and for that example state exactly how cascade control works (whatwould be measured, what is set, and how the controller logic works).
