Draw a complete P&ID of a flow suction tank indicating all control & protection equipment. Indicate all its inlets and outlets. Explain the controls for this system

Answer Posted / Santosh Shaw

Creating a detailed P&ID for a flow suction tank requires a visual diagram that may not be suitable for this format, but I can describe it here: The main inlet supplies raw water to the tank through a strainer to prevent large debris from entering. A level switch and a pressure switch control the inflow and outflow of the water. The level switch sends a signal to a controller when the water level reaches a certain point, triggering the pump to start or stop. The pressure switch does the same based on the pressure in the tank. An overflow pipe prevents the tank from overflowing. A valve controls the flow of water out of the tank. Protective equipment may include check valves, non-return valves, and safety relief valves.
