- Q1. Tell me about yourself
- Q2. Explain functioning of pump
- Ans.
A pump is a mechanical device used to move fluids from one place to another by creating pressure.
Pumps work by converting mechanical energy into fluid flow.
They typically consist of an inlet, an outlet, and a mechanism to move the fluid.
Examples include centrifugal pumps, diaphragm pumps, and piston pumps.

- Q6. Explain About RT, UT, and magnetic partials
- Ans.
RT, UT, and magnetic partials are non-destructive testing methods used in engineering.
RT stands for Radiographic Testing and uses X-rays or gamma rays to inspect the internal structure of a material.
UT stands for Ultrasonic Testing and uses high-frequency sound waves to detect flaws or defects in a material.
Magnetic particle testing uses magnetic fields and iron particles to detect surface and slightly subsurface defec...
