please provide the code methode of question (b).

thank u

The gravity draining tank in Figure 1 has a linear valve (i.e., Fi=KvPv ) and the outlet flow can be considered to follow square root law (i.e., Fo=Khh1/2 ). The tank is 100cm high and has an inner diameter of 25cm. The normal steady-state operation is: h=49cm,Pv=50%open Other process parameters: Kv=70min%openml,Kh=500mincm21ml,=62.4cm3lb Perform each of the following: a) Develop a dynamic model for this process. State all of your assumptions and classify each of the variables. b) Simulate each of the following step changes using an ODE solver in Matlab and plot how level will change with time Pv=10%,20%
