ICP-OES is a technique used for elemental analysis in which a sample is vaporized and excited by a plasma to emit light.

• ICP-OES stands for Inductively Coupled Plasma Optical Emission Spectroscopy.

• It is used to determine the concentration of elements in a sample.

• The sample is vaporized and excited by a plasma to emit light, which is then analyzed to determine the elemental composition.

• ICP-OES is commonly used in environ...read more

Weight chemical analysis of chromite ore involves determining the percentage of various elements present in the ore.

• The ore is first crushed and ground into a fine powder.

• The powder is then mixed with various chemicals to dissolve the elements of interest.

• The resulting solution is then analyzed using various techniques such as atomic absorption spectroscopy or inductively coupled plasma mass spectrometry.

• The percentage...read more

Fault level is the maximum current that can flow through a power system during a fault.

• Fault level is a measure of the system's ability to handle fault currents.

• It is important to calculate fault level to ensure the safety and reliability of the power system.

• Fault level can be calculated by considering the impedance of the system and the available fault current sources.

• The calculation involves determining the maximum f...read more

I would assess the situation, prioritize based on urgency and impact on operations, and make a fair decision considering the needs of the team and the business.

• Assess the reasons for leave requests - urgent personal matters, planned vacations, etc.

• Prioritize based on urgency and impact on operations - critical tasks, team workload, upcoming deadlines.

Sharp corners are avoided in casting to prevent stress concentration and improve the overall strength and quality of the casting.

• Sharp corners can lead to stress concentration, which can cause cracks or failure in the casting.

• Rounded corners distribute stress more evenly, reducing the likelihood of defects.

• Sharp corners can also create difficulties during the casting process, such as mold filling and solidification iss...read more
