Question

system responds to pressure changes as if it were a first-order process in parallel with a second-order process.
The gain of the first order process is -3 and the time constant equals 20 min. The actual output Pm (not the deviation variable Pm) is from a step change in P from 4 to 6 psi and is seen plotted below.

system responds to pressure changes as if it were a first-order process in parallel with a second-order process. The gain of the first order process is -3 and the time constant equals 20 min. The actual output Pm (not the deviation variable P m) is from a step change in P from 4 to 6 psi and is seen plotted below. FIND: Determine Q(t). b) What are the values of K, tau, and (zeta)?

Explanation / Answer

Overall process gain = 27.5/18 = 1.52
