I need help with question 2: Draw a Simulink/block diagram for the model. Simulate the nonlinear model in MATLAB/Simulink, giving suitable inputs, such as step.

I also need help with question 3

We would like to control the water level in a open gas-liquid separator tank that looks like a cylinder with cross-sectional area, A=2m2. A differential equation that describes the changes of the water volume is: V=FinFout, where V is the volume of water, Fin is the water input flow and Fout is the outgoing water flow. Fin=0.1sm3 is a constant. The output flow through a valve can be obtained from: Fout=Cuh, where C=0.25 is a constant, u is the opening percentage of the valve and h is the water level in the tank. 1. Write the (nonlinear) dynamic model, with the water level, h, in the tank as output and the valve opening, u, as input. 2. Draw a Simulink/block diagram for the model. Simulate the nonlinear model in MATLAB/Simulink, giving suitable inputs, such as step. 3. Develop a PID controller to stabilize h, when the initial output is 0m. 4. Investigate the need for integral anti-windup
