COULD YOU SOLVE URGENT PLEASE ?

The organ shown below is controlled by a proportional controller. A liquid carries a drug into an organ of volume Vcm3 at a rate q1cm3/min and also water added at a rate of 1cm3/min and leaves at a rate 1 cm3/min. (Assume; outlet flow=inlet flow) The concentration of drug in the solution leaving the organ is controlled by adding a concentrated drug through a control valve. The following data apply: 1. Concentration of concentrated drug solution C1=25g drug /cm3 solution. 2. Controlled concentration C=0.1g drug /cm3 solution. 3. Control valve: The flow through the control valve varies from 0.002 to 0.0006cm3/min with a change of valve-top pressure from 3 to 15Pa. This relationship is linear. 4. Distance velocity lag: It takes 1min for the solution leaving the tank to reach the concentration-measuring element at the end of the pipe. 5. Neglect lags in the valve. a) Place in each block the appropriate transfer function using above date. Calculate all the constants and give the units
