Stream-oriented socket programs generally follow a prescribed sequence. See Figure 1 for a diagram of the logic flow for a typical client and server. As you study this diagram, keep in mind the fact that a concurrent server typically starts before the client does, and waits for the client to request connection at step 3.

The following figure-1 represents a typical process flow diagram (PFD) for a centrifugal compressor system. Common equipments included in such systems are compressors, driver motors or turbines, suction knock out drums (KOD) to remove traces of liquid from the gas going into the centrifugal compressor and aftercoolers which help lower the temperature of the discharge gas from compressor.

Apr 11,  · The business process flow diagram is (as per its name) flow, so you need to order these activities. Make a list in chronological order. 3. Choose the correct symbols for each activity. There are various notations used to draw process flow diagrams. Thus, correctly indicating each type of activity, using the right symbols, will make it much

Alton T. Tabereaux, Ray D. Peterson, in Treatise on Process Metallurgy: Industrial Processes, 2.5.1.1 Impact of Different Bauxites on the Bayer Process. The Bayer process is basically used for the extraction of aluminum hydrate from the bauxite ores with the mass ratio of alumina to silica (A/S) above 9. The sinter process is widely used to process the poor-grade diasporic bauxite ores

Data Flow Diagram: Similar to a flowchart, this diagram focuses solely on the data that flows through a system. Value Stream Mapping: Part of Lean Manufacturing principles, value stream mapping demonstrates the current state and helps to design the future state of a process, focusing on taking products and services from their beginning to their

Medical Services Flowchart. Managing a medical or dental office can be hectic between trying to juggle phone calls, patients, doctors and staff. Having a well documented process can help clarify the flow of activity so everyone understands where their role fits in. This medical services flowchart template presents one method of office organization.

Process Flow Diagram of Plastics Injection Molding Material The plastics resin used in this work was polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) blend manufactured by Bayer. The trade name of the resin is BayBlend® FR 2010. The resin was dried at 200 °F with a dehumidifying dryer for four hours before processing parts.

Nov 17, · This chapter covers different types of chemical process diagrams, how these diagrams represent different scales of process views, one consistent method for drawing process flow diagrams, the information to be included in a process flow diagram, and the purpose of operator training simulators and recent advances in 3-D representation of different chemical processes.

Flow chart diagrams can be useful for descri programming logic or understanding a single sequence of process activities. It is important to recognize, however, that DFDs are not flow charts. Flow charts often show both processing steps and data "transfer" steps (e.g., steps that do not "process" data); DFDs only show "essential" processing

Nov 17, · The process flow diagram (PFD) represents a quantum step up from the BFD in terms of the amount of information that it contains. The PFD contains the bulk of the chemical engineering data necessary for the design of a chemical process. For all of the diagrams discussed in this chapter, there are no universally accepted standards.
