Trainee Production Engineer Interview Questions and Answers for Freshers

Modes of heat transfer include conduction, convection, and radiation. Valves types include gate, globe, ball, and butterfly. Distillation is a separation process. Azeotropic distillation is a special type of distillation. P&ID diagrams show process flow. Fourier's law relates to heat transfer. Material balance ensures conservation of mass. Boiling point of methanol is 64.7°C. Boiling point of crude oil products varies. Process control involves monitoring and adjusting process...read more

Types of dryers include tray dryers, rotary dryers, fluidized bed dryers. Heat and mass transfer are analogous processes. Multi effect evaporator uses multiple stages to efficiently evaporate liquids.

• Types of dryers: tray dryers, rotary dryers, fluidized bed dryers

• Heat and mass transfer are analogous in that both involve the movement of energy or particles from one place to another

• Multi effect evaporator uses multiple stages to evaporate liquids, with each stage utilizing the...read more

Induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.

• Consists of a stator and a rotor

• Stator has a set of three-phase windings

• Rotor is made up of conductive bars

• When AC current is supplied to the stator, a rotating magnetic field is produced

• This magnetic field induces a current in the rotor bars, which in turn produces a magnetic field

• The interaction between the two magnetic fields causes the rotor to rotate

• Use...read more

CT and PT transformers are used to measure high voltage and current in power systems.

• CT stands for Current Transformer and PT stands for Potential Transformer.

• CT transformers are used to measure high current in power systems and step down the current to a level that can be measured by instruments.

• PT transformers are used to measure high voltage in power systems and step down the voltage to a level that can be measured by instruments.

• Both CT and PT transformers are used for pr...read more
