An open liquid surge system (p = constant) is designed with a side tank that normally is isolated from the flowing material as shown in figure.

(a) In normal operation, Valve 1 is closed (R₁ ? ?) and q₁ = 0. What is the transfer function relating change in q₀ to changes in outflow rate q₂ under these conditions?

(b) Someone inadvertently leaves Valve 1 partially open (0 1

(c) That do you know about the form of the transfer function Q?₂ (s) / Q?₀(s) for Valve 1 partially open? Discuss but do not derive.

(d) Is the response to changes in q₀ faster or slower for Case (b) compared to Case (a)? Explain why but do not derive the response.
