I want to briefly summarize what he is talking about and what you conclude.. the two graph pls urgent(ventilation system)
The pressure of a reactor vessel can be adjusted bychanging either the inlet or outlet gaseous flow rate. Theoutlet flow is kept fixed as long as the tank pressure remainsbetween 100 and 120 psi, and pressure changes are treatedby manipulating the inlet flow control valve. However, if thepressure goes higher than these limits, the exit gas flow isthen changed. Finally, if the pressure exceeds 200 psi, a ventvalve on the vessel is opened and transfers the gas to a storagevessel. Design a control scheme that meets the performanceobjectives.
