In a liquid storage system with a pump as shown in the figure, a liquid with a constant density is stored in a cylindrical tank. The diameter of the tank is 2 ft and the unit of flow rate is ft/min. The initial steady state values of the liquid level and the inflow flow rate are hs= 2 ft, and qi,s =5ft/min. Answer the following question if the inflow flow rate changes to 7 ft3/min when t=0. -: 6 ft h q= Constant 2 ft 1 1 1 1) Defining deviation variables of qi, h, q as a = qi-qis , h=h hs, 7 = q - 9s, find - the transfer function of this process from the material balance equation. 2) The tank is 6 ft high. Determine if the liquid in the tank will overflow, and if it does, find the overflow time
