Solve the below example correctly and urgently, thank you Chemical Process Control Course

(a) Find the steady-state outlet volumetric flow rate (q) and liquid height (h)? Assumptions: - Adiabatic and isothermal process. - Incompressible fluid (Liquid). - Friction in the outlet pipe segments is negligible (short segment). - Steady-state Mechanical Energy Balance (MEB) is applicable for this unsteady flow. - The valve loss coefficient, Cv, does not vary with flow rate. (b) Suppose that inlet volumetric flow rate, qi, changes suddenly from 6 to 9L/s and remains at this new value (step change in qi ), how the liquid height varies with time. How long does it take to reach the new steady state value
