- 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. e) Using the given information, write the general forms of Gm, GIP, and Gv below(in terms of…arrow_forwarda) Briefly explain what ratio control is.
