R R Electricals Interview Questions and Answers

Draw reactor P&ID with safety equipment

• Include reactor vessel, heat exchanger, pumps, valves, and instruments

• Add safety equipment such as relief valves, pressure gauges, and emergency shutdown systems

• Label all components and connections clearly for easy understanding

I studied various unit operations including material handling, quality control, inventory management, and process optimization.

• Material handling techniques such as batching, mixing, and packaging

• Quality control methods like statistical process control and Six Sigma

• Inventory management strategies such as ABC analysis and Just-In-Time

• Process optimization tools like Lean manufacturing and Kaizen

Types of reactors include batch, continuous stirred-tank, plug flow, and fluidized bed reactors.

• Batch reactors: operate for a fixed amount of time before being emptied

• Continuous stirred-tank reactors: have continuous flow of reactants and products

• Plug flow reactors: have perfect mixing in the axial direction

• Fluidized bed reactors: solid particles are suspended in a fluid and react with the fluid

Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.

• Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps: move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps: move fluid parallel to the pump shaft.

• Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, Axial flow pump - propeller pump

The thickness of an autoclave can vary depending on the model and manufacturer.

• The thickness of an autoclave chamber typically ranges from 6mm to 12mm.

• The thickness of the autoclave walls can be influenced by factors such as pressure rating and material composition.

• Some autoclaves may have additional insulation layers to maintain temperature and pressure.

• It is important to consult the manufacturer's specifications for accurate information on autoclave thickness.

An autoclave is a device used to sterilize equipment and supplies by subjecting them to high pressure saturated steam.

• Autoclaves use high pressure and high temperature steam to kill bacteria, viruses, and other microorganisms on equipment and supplies.

• They are commonly used in medical and laboratory settings to ensure that instruments are sterile before use.

• Autoclaves are also used in tattoo parlors, beauty salons, and other industries where sterilization is important.

• Some au...read more
