please do not send ch*tgpt answers and i need the answer in 2 hours please :)

In the top of the distillation column, concentration of overhead vapor product (primary variable, Y2 ) and temperature of the top of column (secondary variable, Y1 ) are controlled using parallel cascade control system. The manipulated variable is the flow rate of reflux stream. In both loops, proportional controllers are used. a. Draw the block diagram of the system. b. Derive the characteristic equations for both loops. c. Suppose the process transfer functions are; -G1(s)=(s+1)21G2(s)=(s+1)31 - Determine the ultimate gain of secondary controller that gives a closed loop damping coefficient of 0.5 in the secondary loop. a. Determine the ultimate gain of primary controller
