Q5. All the process in RAC .
Ans. 
RAC stands for Refrigeration and Air Conditioning. It involves various processes like compression, condensation, expansion, and evaporation.
• Compression: The refrigerant gas is compressed to increase its temperature and pressure.

• Condensation: The high-pressure gas releases heat and condenses into a liquid.

• Expansion: The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature.

• Evaporati...read more

Q1. What is the magnetic particle test procedure
Ans. 
Magnetic particle test is a non-destructive testing method used to detect surface and near-surface flaws in ferromagnetic materials.
• The test involves magnetizing the component, applying magnetic particles to the surface, and inspecting for indications of defects.

• Defects such as cracks, laps, seams, and inclusions can be detected using this method.

• The test can be performed using either dry magnetic powder or wet fluores...read more
