  152.  
  153. This block diagram uses contraint and unknown blocks to determine flows and pressures. A PI control is used to adjust the valve area required to maintain a desired mass flow. The desired mass flow is set by the slider block.
  154.  
  155. An interesting problem is that the mass flow sensor is located 15 feet down stream of the valve; thus the delay time between actual flow at the valve and measured flow depend on the velocity of the flow itself.
