(ii)

For level control loop :

Manipulated variable: flow of fluid

controlled variable: Temperature of tower

Temperature control loop :

Manipulated variable : Steam flow rate

controlled variable : Temperature of tower

(iii) the sign of process gain Kp is Positive.

Because number of zeros on the righ hand side of the graph is more than of left hand side.

(iv)

the control valve is fail to open.

(v)

The sign of the controller gain Kc is positive.

Because any changes made in inlet of controller will results in right change in result
