Nahars Engineering India Interview Questions and Answers

A centrifugal pump is a mechanical device used to move fluids through the conversion of rotational kinetic energy to hydrodynamic energy.

• It works by using an impeller to rotate the fluid and create a centrifugal force that moves the fluid through the pump.

• It is commonly used in industrial and commercial applications to move liquids such as water, chemicals, and petroleum products.

• Centrifugal pumps are classified based ...read more

2-stroke engines have a power stroke every revolution, while 4-stroke engines have a power stroke every other revolution.

• 2-stroke engines are simpler and lighter than 4-stroke engines.

• 2-stroke engines have a higher power-to-weight ratio than 4-stroke engines.

• 4-stroke engines are more fuel-efficient and have a longer lifespan than 2-stroke engines.

• 2-stroke engines are commonly used in small, handheld equipment like chai...read more

A crankshaft is a mechanical component that converts reciprocating motion into rotational motion.

• It is a shaft with one or more offset cranks.

• It is used in internal combustion engines to convert the up-and-down motion of the pistons into rotational motion.

• It is typically made of steel and undergoes rigorous quality inspections to ensure proper functioning.

• The design and construction of the crankshaft can affect the eng

The list count of micrometre is typically 50 or 100.

• The list count of micrometre refers to the number of divisions on the micrometre scale.

• The most common list counts for micrometres are 50 and 100.

• A micrometre with a list count of 50 will have 50 divisions on the scale, while one with a list count of 100 will have 100 divisions.

• The list count determines the precision of the micrometre measurement.
