TCS iON Interview Questions and Answers

A centrifugal pump is a mechanical device used to transport fluids by converting rotational energy into hydrodynamic energy.

• Centrifugal pumps are commonly used in industries such as oil and gas, water treatment, and chemical processing.

• They work by using an impeller to create a centrifugal force that pushes the fluid towards the pump outlet.

• The impeller rotates at high speeds, generating kinetic energy that is then converted into pressure energy.

• Centrifugal pumps are efficien...read more

Some mathematical formulas for area of circle, volume of cone, and volume of sphere.

• Area of circle: A = πr²

• Volume of cone: V = (1/3)πr²h

• Volume of sphere: V = (4/3)πr³

A gear is a mechanical device that transmits rotational motion and power between two or more rotating shafts.

• Gears are used in various machines and mechanisms to change the speed, torque, and direction of rotation.

• They consist of toothed wheels that mesh together to transmit power.

• Different types of gears include spur gears, helical gears, bevel gears, worm gears, etc.

• Spur gears are the most common type, with straight teeth parallel to the gear axis.

• Helical gears have angled ...read more

PH is a measure of acidity or alkalinity of a solution on a scale of 0-14.

• PH stands for 'potential of hydrogen'.

• A solution with a PH of 7 is neutral, below 7 is acidic, and above 7 is alkaline.

• The PH scale is logarithmic, meaning a change of one unit represents a tenfold change in acidity or alkalinity.

• Examples of PH values: lemon juice (2), vinegar (3), coffee (5), pure water (7), baking soda (9), bleach (12).
