Q1. Difference between pressure relief valve and pressure reducing valve.
Ans. 
Pressure relief valve releases excess pressure to prevent damage, while pressure reducing valve reduces pressure to a desired level.
• Pressure relief valve is used to protect equipment from overpressure by releasing excess pressure to the atmosphere.

• Pressure reducing valve is used to reduce the pressure of a fluid to a desired level in a system.

• Pressure relief valves are typically found in systems where pressure buildup ...read more

Q2. Advantage of hyd piston pump over fixed displacement vane pump.
Ans. 
Hydraulic piston pumps offer higher efficiency, variable flow rates, and better control compared to fixed displacement vane pumps.
• Hydraulic piston pumps have higher efficiency due to their ability to vary flow rates based on demand, reducing energy consumption.

• Piston pumps provide better control over fluid flow and pressure, making them suitable for applications requiring precise operation.

• Piston pumps are more durable...read more

Q3. All the laws of thermodynamics and haet transfer in thermal engineering .
Ans. 
Thermodynamics and heat transfer are fundamental principles in thermal engineering, governing energy transfer and conversion.
• First law of thermodynamics: Conservation of energy, stating that energy cannot be created or destroyed, only transferred or converted.

• Second law of thermodynamics: Entropy always increases in a closed system, leading to the direction of heat flow.

• Third law of thermodynamics: As temperature appro...read more

Q5. All the process in RAC .
Ans. 
RAC stands for Refrigeration and Air Conditioning. It involves various processes like compression, condensation, expansion, and evaporation.
• Compression: The refrigerant gas is compressed to increase its temperature and pressure.

• Condensation: The high-pressure gas releases heat and condenses into a liquid.

• Expansion: The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature.

• Evaporati...read more

Q1. Can we use TIA Portal in S7-300 cpu?
Ans. 
No, TIA Portal is not compatible with S7-300 CPU.
• TIA Portal is designed for newer Siemens PLCs like S7-1200 and S7-1500, not S7-300.

• For S7-300 CPUs, Step 7 software should be used for programming.

• TIA Portal offers advanced features like integrated safety, motion control, and HMI design.

• S7-300 CPUs are older models with limited capabilities compared to newer PLCs.

Q2. Difference between encoder and resolver?
Ans. 
Encoder provides digital output while resolver provides analog output.
• Encoder converts mechanical motion into digital signals, resolver converts mechanical motion into analog signals.

• Encoder is more accurate and provides higher resolution compared to resolver.

• Resolver is more robust and reliable in harsh environments due to lack of sensitive electronics.

• Examples: Encoder - optical encoder, magnetic encoder. Resolver - ...read more
