Round 1 - Technical 

(8 Questions)

  • Q1. Explain refrigeration cycle.
  • Ans. 

    Refrigeration cycle is a process in which refrigerant absorbs heat from a low-temperature space and rejects it in a high-temperature space.

    • Refrigerant absorbs heat from the low-temperature space (evaporator)

    • Refrigerant is compressed to increase its temperature and pressure

    • High-temperature refrigerant releases heat in the condenser

    • Refrigerant expands in the expansion valve to lower its temperature and pressure

    • Cycle repe

  • Q4. What is approach of cooling tower.
  • Ans. 

    Cooling towers are heat rejection devices that use water to transfer heat from a system into the atmosphere.

    • Cooling towers work on the principle of evaporation to remove heat from the water being circulated through the tower.

    • The hot water is pumped to the top of the tower and distributed over the fill or packing, where it is exposed to air.

    • As the water flows over the fill, some of it evaporates, which removes heat from...

  • Answered by AI
  • Q5. Why deaerator is being placed at higher elevation?
  • Ans. 

    Deaerator is placed at higher elevation to create a pressure difference for efficient removal of dissolved gases from feedwater.

    • Higher elevation creates a pressure difference which aids in the removal of dissolved gases from feedwater

    • This helps in preventing corrosion in the boiler system

    • It also improves the efficiency of the boiler by reducing the amount of oxygen in the feedwater

  • Answered by AI
  • Q6. What is LP dosing?

  • Q7. What is stroke length of reciprocating compressor?
  • Ans. 

    Stroke length of a reciprocating compressor is the distance the piston travels from top dead center to bottom dead center.

    • Stroke length is an important parameter in determining the displacement volume of the compressor.

    • It is typically measured in inches or millimeters.

    • For example, a reciprocating compressor with a stroke length of 4 inches will have a piston that travels 4 inches up and down within the cylinder.

    • Stroke ...

  • Answered by AI
  • Q8. What is surging and choking in centrifugal compressor?
  • Ans. 

    Surging and choking are two common operating conditions in centrifugal compressors.

    • Surging occurs when the flow rate through the compressor is reduced to the point where the compressor cannot maintain a stable flow and pressure. This leads to a pulsating flow and can cause damage to the compressor.

    • Choking happens when the flow rate through the compressor is increased to the point where the compressor cannot handle the ...
