Q1. What is the axial float of multi stage centrifugal pumps?
Ans. 
Axial float is the movement of the rotor along the axis of rotation in multi stage centrifugal pumps.
• Axial float is necessary to accommodate thermal expansion and contraction of the pump components.

• It helps prevent damage to the pump due to thermal stresses.

• Proper axial float ensures smooth operation and prolongs the life of the pump.

• Example: In a multi stage centrifugal pump, the axial float may be around 0.5mm to 1mm

Q2. Explain double effect vapour absorbption cycle?
Ans. 
Double effect vapour absorption cycle is a type of refrigeration cycle that uses two separate absorption cycles to improve efficiency.
• Consists of two separate absorption cycles: high temperature and low temperature

• High temperature cycle generates vapour from the refrigerant by absorbing heat

• Low temperature cycle uses the generated vapour to produce cooling effect

• Overall efficiency is higher compared to single effect ab

Q3. Describe vapour compression Cycle?
Ans. 
Vapour compression cycle is a thermodynamic process used in refrigeration and air conditioning systems.
• Involves four main components: compressor, condenser, expansion valve, and evaporator

• Refrigerant is compressed in the compressor, raising its temperature and pressure

• High-pressure, high-temperature refrigerant then flows to the condenser where it releases heat to the surroundings and condenses into a liquid

• Liquid refr...read more
