Kirloskar Oil Engines Design Engineer Interview Questions, Process, and Tips

Q1. What is the casting solidification time?
Ans. 
Casting solidification time is the duration it takes for molten metal to solidify in a casting process.
• Casting solidification time depends on factors like material type, mold temperature, and casting geometry.

• Higher pouring temperatures generally result in shorter solidification times.

• Thicker sections of the casting will take longer to solidify compared to thinner sections.

• Aluminum alloys typically have shorter solidif

Q1. HOW TO CALCULATE CT CURRENT
Ans. 
CT current can be calculated by dividing the primary current by the turns ratio of the current transformer.
• CT current = Primary current / Turns ratio

• Primary current is the current flowing through the primary conductor

• Turns ratio is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding

Q5. WHAT IS LSC 2A AND LSC 2B
Ans. 
LSC 2A and LSC 2B are standards for lighting in commercial and industrial buildings.
• LSC 2A and LSC 2B are part of the Lighting Power Density (LPD) requirements in building codes.

• LSC 2A is for commercial buildings while LSC 2B is for industrial buildings.

• They specify the maximum allowable power consumption for lighting per unit area in a building.

• For example, LSC 2A may require a maximum LPD of 0.9 watts per square foot
