Reliance Industries Interview Questions, Process, and Tips

Different types of pumps and their differences.

• Centrifugal pumps: used for low viscosity fluids, high flow rates, low pressure

• Positive displacement pumps: used for high viscosity fluids, low flow rates, high pressure

• Axial flow pumps: used for high flow rates, low pressure, low viscosity fluids

• Mixed flow pumps: used for medium flow rates and pressures

• Jet pumps: used for pumping fluids with high solids content

• Differences...read more

Boilers are vessels that heat water or other fluids to generate steam or hot water for various applications.

• Fire-tube boilers: hot gases pass through tubes immersed in water

• Water-tube boilers: water flows through tubes and hot gases surround them

• Electric boilers: use electricity to generate heat instead of burning fuel

• Condensing boilers: extract additional heat from the exhaust gases to increase efficiency

• Package boile...read more

Pumps move liquids, compressors move gases.

• Pumps are used to move liquids from one place to another, while compressors are used to increase the pressure of gases.

• Pumps are typically used in industries such as water treatment, oil and gas, and chemical processing, while compressors are used in industries such as refrigeration, air conditioning, and power generation.

• Examples of pumps include centrifugal pumps, positive d...read more

Refrigeration cycles are thermodynamic cycles used in refrigeration systems to transfer heat from a low-temperature region to a high-temperature region.

• Refrigeration cycles involve four main components: compressor, condenser, expansion valve, and evaporator.

• The cycle starts with the compressor, which increases the pressure and temperature of the refrigerant gas.

• The high-pressure gas then flows into the condenser, where...read more

Creep is the gradual deformation of a material under constant stress. Failure is the inability of a material to perform its intended function. Fracture is the separation of a material into two or more pieces due to stress.

• Creep occurs over time and can lead to permanent deformation.

• Failure can occur due to various reasons such as overloading, fatigue, corrosion, etc.

• Fracture can be ductile or brittle depending on the m...read more

Hardness is resistance to indentation while toughness is resistance to fracture.

• Hardness is a measure of how easily a material can be scratched or dented.

• Toughness is a measure of how much energy a material can absorb before fracturing.

• Hardness is often measured using the Mohs scale, while toughness is measured using impact tests.

• For example, diamond is very hard but not very tough, while rubber is not very hard but ve
