Raymond Lifestyle Limited Associate Engineer Interview Questions and Answers

Critical radius of insulation is the thickness of insulation at which heat loss through the insulation is minimum.

• It is the point where the heat transfer rate is at its minimum.

• It is important in designing insulation systems.

• It depends on the thermal conductivity of the insulation material and the temperature difference across the insulation.

• If the insulation thickness is less than the critical radius, the heat loss wi...read more

Points on a stress-strain diagram represent specific stages of material deformation.

• The elastic limit is the point where deformation is reversible.

• The yield point is where plastic deformation begins.

• Ultimate strength is the maximum stress a material can withstand.

• Fracture point is where the material breaks.

• The modulus of elasticity is the slope of the linear portion of the curve.

• Each point on the diagram represents a s

ICP OES is a technique used for chemical analysis of chromite ore.

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

• It is a powerful analytical technique used for the determination of trace elements in a variety of matrices.

• ICP OES can be used to determine the concentration of elements such as Cr, Fe, Mg, Al, and Si in chromite ore.

• The technique involves the excitation of atoms in a sample usi...read more

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
