2: Consider the following process is use to maintain the level of water in the tank ig-2) 10-marks Given condition: - Level controller: Proportional only, Reverse action - Range of level transmitter: 0 to 60 inches - PB=80%, - Bias or controller output at equilibrium =50% - Set point =35 inches. - Load: Q= fixed at 3 gpm - Valve: Pressure drop P is constant, linear characteristic, delivers 5 gpm at 100% stroke. For the automatic controller, calculate the controller output in % and the actual level in inch under steady-state condition. Fig-2 Tank Level control
