CENG 471 - Process Control Lab

 Spring 2000

DATA:

Volume of tank 1 = 160 ml

Volume of tank 2 = 160 ml

Volume of tank 3 = 290 ml

Flowrate of pure water = 600 ml

Note: This flowrate should be kept constant at all times

 

Concentration of salt solution = 14 (g salt)/(l of solution)

STEP TEST:

• Specify a file name and start LabView program.
• Set manually the water pump flow rate to 600 ml/min
• Set the salt pump flow rate to 50 ml/min.
• Wait for output salt concentration to stabilize.
• Set the salt pump flow rate to 150 ml/min.
• Wait for output salt concentration to stabilize.
• Stop LabView program.

PULSE TEST:

• Specify a file name and start LabView program.
• Set manually the water pump flow rate to 600 ml/min.
• Make sure that the output salt concentration is zero.
• Set the salt pump flow rate to 225 ml/min.
• Count to 8 and set the salt pump flow rate back to zero.
• Wait for output salt concentration to come back to zero.
• Stop LabView program.
