Technocare Solutions Interview Questions and Answers

Types of pumps include centrifugal, reciprocating, and rotary pumps. Heat transfer modes include conduction, convection, and radiation.

• Types of pumps: centrifugal, reciprocating, rotary

• Heat transfer modes: conduction, convection, radiation

• Heat transfer coefficient: measure of how well a material transfers heat

• Mass transfer coefficient: measure of how well a material transfers mass

Steelmaking is the process of producing steel from iron ore and/or scrap metal through various methods such as blast furnaces or electric arc furnaces.

• Iron ore is first mined and then processed to remove impurities.

• The purified iron ore is then combined with coal and limestone in a blast furnace to create molten iron.

• The molten iron is further processed to remove impurities and adjust the carbon content to create steel.

• Alternatively, scrap metal can be melted in an electric a...read more

Various types of pumps and valves are used in industries for different applications.

• Types of pumps: centrifugal pumps, positive displacement pumps, diaphragm pumps, gear pumps

• Types of valves: gate valves, globe valves, ball valves, butterfly valves

• Pumps and valves are used in industries such as oil and gas, water treatment, chemical processing

• Each type of pump and valve has specific characteristics and applications

The driving force of heat and mass transfer is the difference in temperature or concentration between two points.

• Temperature difference drives heat transfer - for example, hot coffee cooling down in a room

• Concentration gradient drives mass transfer - for example, diffusion of perfume in a room

There are three main modes of heat transfer: conduction, convection, and radiation.

• Conduction: Heat transfer through direct contact between particles. Example: Touching a hot stove.

• Convection: Heat transfer through the movement of fluids (liquids or gases). Example: Boiling water.

• Radiation: Heat transfer through electromagnetic waves. Example: Sunlight warming the Earth.
