Lupin Engineering Supervisor Interview Questions and Answers

Tablets can have different types and defects.

• Types of tablets include chewable, effervescent, and extended-release.

• Common defects in tablets include chipping, cracking, and discoloration.

• Other defects can include improper dosage, inconsistent dissolution, and poor packaging.

• Examples of tablet defects: a cracked tablet, a discolored tablet, or a tablet with inconsistent dissolution.

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• A chiller is used to cool down water or other fluids in industrial or commercial settings.

• There are two types of chillers: vapor-compression and absorption.

• Compressors are used in refrigeration systems to compres...read more

There are several types of pumps used in various industries.

• Centrifugal pumps

• Positive displacement pumps

• Axial flow pumps

• Mixed flow pumps

• Jet pumps

• Submersible pumps

• Diaphragm pumps

• Gear pumps

• Peristaltic pumps

• Rotary lobe pumps

• Screw pumps

• Vane pumps

The pump parts can differ in terms of material, size, shape, and function.

• Different pumps may have different impellers, casings, shafts, bearings, and seals.

• The material used for the parts can vary depending on the type of fluid being pumped and the environment.

• The size and shape of the parts can also vary depending on the flow rate and pressure requirements.

• The function of the parts can differ based on the type of pum...read more

Solenoid valve works on the principle of electromagnetism to control the flow of fluids or gases.

• It consists of a coil, plunger, and valve body

• When the coil is energized, it creates a magnetic field that pulls the plunger towards it

• This movement opens or closes the valve, allowing or blocking the flow of fluid or gas

• Used in various applications such as refrigeration, HVAC systems, and industrial automation

Gears are mechanical components that transmit power and motion between rotating shafts. Two-stroke and four-stroke engines are types of internal combustion engines.

• Gears are used to change the speed, torque, and direction of power transmission.

• Two-stroke engines have a simpler design and are lighter than four-stroke engines.

• Four-stroke engines are more fuel-efficient and produce less pollution than two-stroke engines.

• B...read more

A latch machine is a digital circuit that stores data and can be used for memory and data storage applications.

• A latch machine is a type of flip-flop circuit that can store a single bit of data.

• It can be used for memory and data storage applications.

• It is commonly used in digital systems such as computers and microcontrollers.

• Examples of latch machines include D-latch, SR-latch, and JK-latch.
