2. The differential equation governing the flow rate out of a liquid in a particular container with an inlet and an outlet is given by 20+302.25 = H where H is the height of the liquid and Q is the flow rate out the hole. If the liquid height is at a steady value hs, the flow rate out is qs. Determine a linearized differential equation for the perturbation in flow rate q(t) if the liquid height is perturbed by h(t) [that is H(t) hs+h(t)]. Note that from binomial expansion: (1 + ε)" (1+nɛ) if ε << 1
