$\begin{array}{l}\displaystyle \frac{d Q_{WAQ}}{dt} + \frac{1}{\tau} Q_{WAQ} = J \cdot ( p_i - p(t))\end{array}$

Derivation

Const PI expansion:

$\begin{array}{l}\displaystyle q_{WAQ} = \frac{d Q_{WAQ}}{dt} = J \cdot ( p_{AQ} - p(t))\end{array}$

Finite-volume reservoir PSS depletion:

$\begin{array}{l}\displaystyle p_{AQ} = p_i - \frac{Q_{WAQ}}{V_{WAQ} c_t}\end{array}$
