Available Information:(i) The three valves operate linearly with resistances R1 R2 R3.(ii) The tank volumes (V1 and V2) are constant.(iii) The Ideal Gas Law holds.(iv) The molecular weight of the gas is M.(v) Operation is isothermal.(b) Develop the model (linearize Laplace transform etc.) just to the point where you can identify the following characteristics of the transfer function(i) Order of the denominator?(ii) Order of the numerator?(iii) Any integrating elements present?(iv) Gain equals one?Note: There is no need to derive the actual transfer function. On the other hand you should justify your answer to eachquestion.
