5. The outflow from a storage tank (A=4m2, maximum liq. height =5m) is forcibly constrained at 0.02m3/s. At a certain "steady state", tank fluid level was 2m. The inflow rate is suddenly decreased by 10%. (a) How is the tank fluid level affected? Does it reach a final 'steady' value? (b) Redo the above problem when there is no constraint on the tank outflow
