A data sheet – process data
A data sheet –material and facility data
A data sheet
• Identify the object – “P_101”
• Classify the intended material object
– Centrifugal pump
– ANSI AA Back Pullout
– “Goulds 3196STD”
• The process
– the fluid that is pumped
• stream identifier
• a classification
– “normal” flow rate
– “design” flow rate
• The facility
– piping connections
– power supply
• Mechanical details
– classifications of parts
– Materials of construction
– dimensions
Identifying classes
• What sort of thing something is
– Centrifugal pump
• iso15926-4:centrifugal_pump
– “ANSI AA Back Pullout”
• ANSI/ASME B73.1-2001
• Back pull-out
• AA (head rating)
– “Goulds 3196STD”
• goulds:3196STD

Going forward to a data base
• Going from a data sheet to a data base is difficult
– custom and practice on the use of data sheets
– people know what the fields are used for
• A data base splits a data sheet into:
– relationships between objects
– properties of objects
which do not have the context of a particular data sheet
• If we refurbish:
– what were requirement on the new pump – which are still important
– what was information about the old pump – which changes
