NPCC Engineering Structural Engineer Interview Questions and Answers

The laws of thermodynamics are fundamental principles governing energy and heat transfer in physical systems.

• First Law: Energy cannot be created or destroyed, only transferred or converted.

• Second Law: Heat naturally flows from hot to cold objects, and entropy tends to increase over time.

• Third Law: As temperature approaches absolute zero, entropy approaches a minimum value.

• Examples: A car engine converting fuel into mot...read more

Hydrotest procedure is a method used to test the integrity and strength of pressure vessels or pipelines.

• Hydrotest involves filling the vessel or pipeline with water or another suitable test medium.

• The pressure is gradually increased to a predetermined level and held for a specified duration.

• During the test, any leaks or weaknesses in the system are identified and addressed.

• The test pressure is typically higher than th...read more

Belt length can be calculated using the formula: L = 2C + (πD)

• Measure the distance around the pulleys (C)

• Measure the diameter of the larger pulley (D)

• Use the formula L = 2C + (πD) to calculate the belt length

• For example, if C = 30 inches and D = 10 inches, then L = 2(30) + (3.14)(10) = 60 + 31.4 = 91.4 inches

Various types of joints used in engineering include welded joints, bolted joints, riveted joints, and adhesive joints.

• Welded joints involve fusing two materials together using heat or pressure.

• Bolted joints use bolts and nuts to secure two materials together.

• Riveted joints involve using rivets to connect two materials.

• Adhesive joints use adhesives to bond materials together.
